How to deactivate automatic volume display in Mesh

Posted by William Tougeron at October 15. 2012
Hi all, Actually I just wanted to know if there is a way to deactivate the automatic display of volumes elements after computing a 3D mesh. Of course it is not a vital problem, but dealing with huge meshes the display of volumes is very slow and rarely necessary (face display is often sufficient). When the mesh is computed from scratch or extruded (in the case of 2D OpenFOAM meshing) it can take a very long time just to display the mesh and then to deactivate the volume display. It would be very great to be able to deactivate the volume display BEFORE displaying the mesh. Or to deactivate the automatic "entity display set-up". I went through the Salome preferences many times but I didn't find anything about this. Attached is a very basic study with a (cleared) meshed cube example. Is it possible to compute and display the mesh without displaying its volumes? Best regards, William

Hi William

Your request is very reasonable. Unfortunately there is no such a possibility is SALOME. We'll try to add this feature (maybe next year).

Best regards
Edward

Hi,

this was way back in 2012. Now we have the year 2016, Salomé 7.7.1. But it's still rather slow at times (I am currently dealing with a 4M tetrahedra 3D mesh). I would like to know if there is such an option now, and if there is any other possibility to speed up mesh computation and display (which runs only on one out of aight cores for me BTW).

Thank you fon an answer,

Matthias

Hi Matthias

1) You can choose to show say edges only. In the mesh popup in OB activate Display Entity > Choose...

2) You can define how many volumes to automatically display. In Mesh Preferences set "Size Limit" and activate "Incremental limit check".

Thank you, that will be useful!
