open TELEMAC-MASCARET The mathematically superior suite of solvers

Indeed on an AMD Threadripper 5975WX 32Cores and NVIDIA RTX A2000 12Gb it does not freeze with 40k nodes. But this is a 5000€ computer.

It should not require a such powerful computer just to select a node...
Selecting a node is a simple task and should be instant even on mesh with millions of nodes.

Many people use a laptop with integrated graphics to build models and offload numerical simulation to clusters. 40k mesh is a small mesh.
I usually build models netween 100k and 500k nodes and I can't select a node or element without freezing the UI so I just export the mesh in a SLF and finish the mesh editing in QGIS or trigrid.

Thank you for sharing your opinion. I'm happy to hear that you have a solution that works for you.

Kindly... Alan

PS If you would like to pay me to solve this issue for you and everyone then please feel free to hire me to do so. Otherwise, get a computer with a reasonably behaving graphics card, NVIDIA cards work fine as far as I know.

Hi all,

This has been a problem with integrated Intel and ATI/Radeon video devices since we built the first EnSim application way back in 1997.

EnSim is implemented using the OpenGL graphics library since the author initially developed EnSim precursor software on Silicon Graphics machines.
Intel and ATI/AMD video drivers have always been buggy in their OpenGL support. Sometimes installing the latest drivers helps.

For that reason we have always recommended NVidia based graphics.
Unfortunately nothing has changed in 27 years.

Hope this helps... Martin

Hi,

I had the same problem when I got a new laptop at work. I followed the steps above in the windiws settings and changed from "let windows decide" to "highest performance" and that worked!

Thanks for sharing
