Crack Abaqus 6.9 License File LINK



From Zencrack version 9.0-1 the plug-in for Abaqus/CAE is revised to only provided functionality to process spline and crack profile data. This is intended to help when partitioning models for the crack-block method. All creation of Zencrack input data should be carried out in the Zencrack GUI.




Crack Abaqus 6.9 License File



From Zencrack versions 7.9-1 to 8.3-1 the Zencrack GUI replaces and improves upon many of the capabilities of the plug-in for Abaqus/CAE provided with those releases. The GUI is the recommended way to create and maintain Zencrack input files. It also provides a means to run Zencrack and to post-process the crack growth profiles. However, the plug-in retains some usefulness when partitioning a geometry as the crack front viewer can be used to display a spline or crack front position on the geometry to help in the partitioning process.

Due to changes in the Python version between Abaqus 6.9/6.10 and 6.13/6.14 there are three sets of files provided with each v7.9-2 - v9.x installation - one for Abaqus 6.8-6.9, one for Abaqus 6.10-6.13 and one for Abaqus 6.14 or later. Up to v7.9-1 only two sets of files were provided. These are suitable for Abaqus 6.8-6.9 and 6.10-6.13 (i.e. the plug-in supplied with versions of Zencrack earlier than v7.9-2 will not work with Abaqus 6.14).


For plug-ins supplied with versions up to v8.3-1 the "picking" capabilities that extract data from a model are only operational from within the Visualization module becuase they require that the model in the viewport is an odb model rather than a model database. The recommended procedure is to generate an uncracked model and run at least a datacheck. Then load the odb file for the model before picking data for the Zencrack input file.


  • For Zencrack 7.7 to 8.3 there are two ways that the number of processors for Abaqus jobs executed by Zencrack can be specified: Variable ZCR_OPTIONS_ABAQUS in the zencrack.ini file (or OPTIONS_ABAQUS for 7.7 and 7.8 in the runzcr script file) can be used to define parameters passed to the Abaqus command line for all Zencrack jobs. The cpus option can be added to this parameter. Refer to the file itself (located in the Zencrack tools folder) or the Installation And Execution Manual for more information about this variable.

The command line option "-fe" can be used when executing a Zencrack job. This defines parameters to be passed to the Abaqus command line for that particular Zencrack job. The parameters should be surrounded by quotes. For example, to use 4 processors:runzcr83 -j jobname -fe "cpus=4" If the cpus parameter is defined using both methods, the command line value takes precedence.


  • Zencrack has three methods for extracting results from Abaqus: Extract results from the Abaqus .odb file - this is the recommended method.

  • Extract results from the Abaqus .dat file - this can have limited precision.

  • Extract results from the Abaqus .fil file - this requires the use of a supplied Abaqus user subroutine, URDFIL, and hence a Fortran compiler must be installed.


In version 7.8 and all earlier releases the default option for extracting contour integral results and nodal displacements from an Abaqus analysis is that the values are taken from the .dat file. However, these values have limited precision. In particular, in a model with both sides of the crack included, it may be that the global displacements near the crack are several orders of magnitude greater than the local crack opening displacements. In such cases the displacement values extracted from the .dat file may be of insufficient precision to allow the local crack opening displacements to be calculated accurately. This results in poor values for the stress intensity factors calculated from the displacements.


Due to changes in the default installation location introduced with the release of Abaqus 2020 the location cannot be automatically detected during setup of Zencrack 8.3-1 or any earlier versions. At installation time Abaqus should not be configured. After installation the settings should be applied manually by editing the tools\zencrack.ini file as indicated below.


The ZCR_ABAQUS and ZCR_ABAQUS_VER entries in the [ABAQUS] section of the zencrack.ini file should be set manually - they cannot be set during installation or subsequently by the "runzcr8x setup" command. ZCR_ABAQUS must point to the ABQLauncher.exe file in the appropriate Abaqus folder for versions 2020 and 2021 or to SMALauncher.exe for Abaqus 2022. The Abaqus version defined by ZCR_ABAQUS_VER should be set to 2020, 2021 or 2022. If the Abaqus location contains spaces, double quotes should be included around the definition of ZCR_ABAQUS.


These versions have not been tested with Abaqus 2020 (or later). However, the issues are expected to be similar to those described in the section "Using Zencrack with Abaqus 2016 to 2019" (including issues related to extraction of results). ZCR_ABAQUS and ZCR_ABAQUS_VER entries should be set to point to the appropriate Abaqus .exe file (as noted above) with the version set to 6.202x.


The ZCR_ABAQUS and ZCR_ABAQUS_VER entries in the [ABAQUS] section of the zencrack.ini file should be set manually - they cannot be set during installation or subsequently by the "runzcr79 setup" command. ZCR_ABAQUS must point to the abqlauncher.exe file in the appropriate Abaqus folder. The Abaqus version defined by ZCR_ABAQUS_VER should be set to 6.2016. If the Abaqus location contains spaces, double quotes should be included around the definition of ZCR_ABAQUS. For example, for 64bit Windows with Abaqus in the default location the [ABAQUS] section includes:


Due to issues related to extraction of the Abaqus version and sub-version used for the analysis, Zencrack versions up to and including 7.9-3 are unable to extract displacement or temperature results from the Abaqus .dat file. Instead it is recommended to extract results from the .odb file. Depending upon whether or not temperature extraction is attempted, one of the following messages will occur:


The plug-ins for Abaqus/CAE supplied with versions of Zencrack up to and including version 7.9-1 will not work with Abaqus 2016 due to a change in the underlying version of Python used in this version of Abaqus. The plugins supplied in the "fe_abaqus\zencrackplugins_6-14_onwards" folder for versions 7.9-2 and 7.9-3 are compatible with Abaqus 2016. The following warning is issued when the plug-ins are loaded by Abaqus/CAE or Abaqus/Viewer:


  • Due to changes in the name of an internal set created by Abaqus in the .odb file, the method of extraction of results from the .odb file may not be able to find any results. The following are affected: Zencrack 7.8-1 to 7.9-1 if using Abaqus 6.14-1 or 6.14-2.

  • Zencrack 7.9-2 to 7.9-3 if using Abaqus 6.14-3, 6.14-4 or 6.14-5.


  • Fail with error 5020 - end of file reading temperatures, or,

  • Give a warning that displacements were not read correctly and end with zero crack growth at all nodes (because the opening status is "closed" for all nodes).


hi all im using abaqus 6.9 to simulate a crack propagation in an elastic material whith Xfem option, i still have this errors :the following XEFM crack are failling to correctly generate the conditions are listed whith the crack names : crack-1 Failed to locate crack tip. and if i submit the job even the warning its abort and i get this error:the damage model has to be specified for enriched element ( nbre) instance part 1-1.i specify the damage model in Intprop as follow ** MATERIALS** *Material, name=Material-1*Elastic 2.1e+11, 0.3*DAMAGE INITIATION,CRITERION=MAXPS8.44E7,*DAMAGE EVOLUTION,TYPE=ENERGY,MIXED MODE BEHAVIOR=POWER LAW,POWER=1.04.22d4,4.22d4,4.22d4*DAMAGE STABILIZATION 1.e-5if any one know wat the problem whith my model tel me plz i have 2 questionshow to specify or indicate the crack tiphow to get enriched elemnt.tanx in advances


about this question 'crack-1 Failed to locate crack tip.'. i have met before. maybe you could remesh your model or change the initial crack longth. it sometimes will helpful. i think it's about abaqus' problem.


i am new to abaqus. i am concerned wittth a slab design involving a crack after cyclic loading. whwnever i try for an xefm crack, i am getting an error like "failed to locate crack tip". i am doing it in cae mode. how can i overcome this error
