I'm supposed to optimize an existing simulation. I noticed that Reading STL comes an "error/warning" that.
Reading STL file 'Meshes/MitAussen.stl' (mesh processing step 1/3)

The contact model you specified is not located in any whitelist.
Because of this the model will be run in an unoptimized version (increasing runtime by up to 20%).
In order to optimize this model you have the following options:
(i) Run the genAutoExamplesWhitelist.sh script in your LIGGGHTS(R) source folder to automatically parse the input script
(ii) Add the model combination by hand to your style_contact_model_user.whitelist that can be found in your LIGGGHTS(R) source folder
If you perform one of the steps above LIGGGHTS(R) needs to be recompiled to generate the optimized code.
I have already added several times the contact model - GRAN_MODEL(HERTZ, TANGENTIAL_HISTORY, COHESION_SJKR, ROLLING_EPSD2, SURFACE_DEFAULT) - recommended to me in the whitelist and recompiled everything with "make clean-all" and then "make auto".
The new contact model is also afterwards in the style_contact_model.h.
Am I doing something wrong or is this a bug or is the contact model compiled and the "warning" is wrong?

Thanks for your help
