MSC.Mvision v3 Export Functions
Update 1
Update is STRONGLY recommended.
Incorrect data exported!
Description
This export function update corrects
an error in the export functions shipped with MVISION Builder and Evaluator
v3. The error is exhibited in the export to all analysis codes except for ABAQUS.
The error occurrs when exporting an isotropic material with strain dependencies
where the export function has to calculate the yield strength from the given
stress vs. strain curve. In calculating the yield strength, the export function
mistakenly reported the ultimate strength as the yield strength. This resulted
in possible errors in the curve created by the export functions.
This error does not occur if the
export function received a yield strength from the databank or the user-entered
a yield strength by typing it on the Export form. The Young's Modulus calculated
by the export function was not affected by this error and was calculated correctly
even when the yield strength was incorrect.
It is strongly advised that all
MSC.Mvision users replace the export functions (expfunc) included as
part of the Version 3 release with the function from this update.
Installation
- Download the the appropriate file
for your platform as listed below:
Put the file in a directory of
your choice where you have write permission.
- From a Unix shell, navigate to
the directory where you put the compressed tar file. Uncompress and untar
the file with the following UNIX command. In place of the <xxx>
type the machine as listed in the table above.
zcat mvexport.<xxx>.tar.Z | tar xvf -
This will leave you with a file
named expfunc.
- Change your login to one that
has permission to write in the directory where MVISION is installed.
- Change directory to the MVISION
intallation and the export_function sub-directory. Rename the existing
expfunc file to another name so the updated expfunc does
not overwrite it (e.g., expfunc_old).
- Copy the new expfunc
file to the $MV_HOME/export_function directory.
The installation is now complete
and you should be able to immediately take advantage of the new updated export
functions. When you are confident that the new function works properly, you
can delete the old expfunc file.
If you should have any problems
or questions, please do not hesitate to contact your local MSC
Support Hotline.
