Hi everyone,

I have a question concerning the preprocessing that for a big mesh have an important time cost.

Is there a way to run only one time the preprocessing and after use only the file listpre.* that was created?

I do not find the way to do taht.
 
Best regards.

Hello,

In the runcase script, you have several options :
 
EXEC_PREPROCESS EXEC_PARTITION EXEC_KERNEL
which allow you do do just this.

Those options are also accessible in the "advanced options" of the batch calculation preparation in the GUI. All you need to do is execute the preprocessor but not the kernel, so that the preprocessor_output will be saved in the first run's RESU directory. You may then copy or ling to it in the DATA subdirectory, and run whilen ot executng the preprocessor.

If you are using the older 1.3 version, the equivalent option in the "lance" file is MODE_EXEC.

Best regards,
