Hi,
I have tried meshing a model in PLAXIS 3D and the error is as follows
Meshing failed with the following error:Fatal: Could not generate mesh.Warning: 351 EMR warnings have been detected. The 15 most severe are listed, the remaining 336 are not shown.Warning: # 1/203 of small 3D proximity: detected size 4.00e-02; this is 4.58e+01 times smaller than minimum targeted element size.

I have tried refining the mesh at the specified surfaces and volumes. I have also tried refining the coarseness of the mesh and still the error remains same.
Kindly suggest any other alternate ways or any solution.

Dear Rohith,
Technically there is no limit but naturally having an enormous number of elements generated will make the calculation inefficient as it may take weeks or months to run.
Especially when a project may have updates that may require to remesh and recalculate, we strongly advise maintaining a manageable size of the number of elements.
As you would expect that highly depends on the project you want to simulate, the level of details, type of calculation, etc..
Hi Stefanos Papavasileiou
Is there any maximum limit for the number of elements in a model?
The total number of elements in my model is around 12 lakh elements.
You have also posted the same here: https://communities.bentley.com/products/geotech-analysis/f/plaxis-soilvision-forum/232702/plaxis-3d-mesh-warning
I have provided feedback.
