Using subroutines written in Fortran 90 with Abaqus Standard

阅读更多关于 Using subroutines written in Fortran 90 with Abaqus Standard

问题 I am using Abaqus with user-defined subroutines. To the best of my knowledge, Abaqus Standard or Explicit can be used with subroutines written specifically in Fortran 77 language, not the improved Fortran 90/95 language! Is there a way how to use Fortran 90 and later with Abaqus? 回答1: By default, Abaqus expects user subroutines to be written in the older fixed-format style. However, you can use just about any modern language feature supported by your compiler. 1 This includes using modules,

Abaqus: A way to localize external nodes?

阅读更多关于 Abaqus: A way to localize external nodes?

问题 Does anyone of you know of (if there exists) a way to extract node numbers of an external surface of a model in Abaqus? By a surface I dont mean an entity, Im talking purely about an outside area of an object. Thanks! 回答1: If you have defined a Set or Surface , getting the nodes is trivial: p = mdb.models[name].parts[name] # Get the Node objects on the previously defined surface: node_objects = p.surfaces[name].nodes # Same from a set: node_objects = p.sets[name].nodes # Get the labels for

How to get the volume of elements with certain type of material in Abaqus ODB by means of Python

阅读更多关于 How to get the volume of elements with certain type of material in Abaqus ODB by means of Python

问题 I need to calculate the total volume of elements with a certain type of material, then calculate that part of them in which some UVARM variable is greater than 1, and then define the ratio between these volumes. The problem is that I cannot find how to filter out the elements exactly by name of material, not by section, part instance or element set, since the elements of interest are evenly distributed among these sections, sets etc. Thank you 回答1: It seems you need to loop over every element

Getting element density from abaqus output database using python scripting

阅读更多关于 Getting element density from abaqus output database using python scripting

问题 I'm trying to get the element density from the abaqus output database. I know you can request a field output for the volume using 'EVOL', is something similar possible for the density? I'm afraid it's not because of this: Getting element mass in Abaqus postprocessor What would be the most efficient way to get the density? Look for every element in which section set it is? 回答1: The properties are associated something like this: sectionAssignment connects section to set set is the container for

Abaqus pre.exe error code 529697949

问题 When I try to submit a job, I always get an error. In log I see this message: The executable pre.exe aborted with system error code 529697949. Please check the .dat, .msg, and .sta files for error messages if the files exist. I don't have these files. I looked for the solution, but the only idea is that there is not enough free space on my hard drive. I have 20GB free. Does anyone know if something else can cause this error? Or does anyone know how much free space I need for submitting a job

Transforming an Abaqus macro into a python script

阅读更多关于 Transforming an Abaqus macro into a python script

问题 I am using Abaqus (6.13) to run FEM thermal simulations. I need to get the total external heat flux aplied on that model. My searches indicated that the only way to get it was to sum de RFLE history output on the whole model and it works fine. The problem is that I have a ~300 000 elements model and that the simple opening of the Report/XY window takes a couple of hours. In order to simplify my exportations, I made an exporting macro with the macro manager of Abaqus. The recording starts

问题 Abaqus is a physics based mechanical simulation tool. It comes bundled with python 2.7.3. I use python scripts to automate certain operations. Recently, I had to run a Python3.5 script through Abaqus CAE python interactive interface using os.system(). subprocess.call or subprocess.popen did not work either. Abaqus python kept giving the following error: Fatal Python error: Py_Initialize: unable to load the file system codec File "C:\SIMULIA\CAE\2016\win_b64\tools\SMApy\python2.7\lib\encodings
