Elmer Discussion Forum

we could leave an option for the user. to compile against the LGPL or the GPL ones. How do you think about that?

thanks for the immediate reply. A couple of questions: is my understanding of the code valid? the array is undefined, right? can we please modularize UMFPACK? instead of including the whole code into the Elmer source code? it is very difficult to find issues and help with the development as is. I al...

I'm checking the source code , and the error is thrown by this block of code: IF (iinfo(1) < 0) THEN PRINT*, 'Error occurred in umf4num: ', iinfo(1) STOP ENDIF the iinfo(1) variable also seems to be populated by CALL umf4num( Rows, Cols, Values, Symbolic, A % UMFPack_Numeric, Control, iInfo ) line. ...

Lucky guess
Can you be kind to tell me in which document are these documented?

I understand that one can normalize a boundary condition (e.g., pressure) by area: Boundary Condition <number> Target Boundries(<number>) = <number> <keyWord> = <value> <keyWord> Normalize By Area = Logical True End But I'm wondering if one can also normalize body forces by volume? something like: B...

OK, at least I'm able now to make structured brick/prisms mesh in Gmsh! The key is to first specify the number of points you want across a specific line: Transfinite Curve{<lineNumber>} = <oddNumber>; then mesh the surfaces: Transfinite Surface{<surfaceNumber>} = {<points>}; and then combine mesh: R...

Thank you, Kevin, I am almost halfway through reverse engineering your implementation. The next step for me is to learn how to generate a proper mesh in Gmsh, like the one you made with SALOME. Although my mesh is much smaller, yours yields more reasonable results. And I do not understand why is that!

for those who end up here, the same issue happened to me. The reason turned out to be the fact that I was storing all the mesh.* files in an OneDrive folder. And the syncing processes might have corrupted some pieces and bits. Copy and pasted the original mesh.* files to a different folder and it wo...

I started from Kevin's 3D model , converted the leaf.unv to Elmer Solver mesh with ElmerGrid.exe 8 2 leaf.unv Though I'm getting a totally different result: I believe Kevin is doing some mesh refinement/modifications through elmerGui that I need to replicate with ElmerGrid in the command line.

to solve the above issue I had to change the order back to 1
