Hi Mustafa,
Have you tried using only linear elements, set order 1 in gmsh?

paste squeeze simulation advice
Hi Elmer group, Referring to the image below maybe someone can offer advice on how to simulate the following 3D problem with Elmer (if possible) or any other tool they might know of that could do it. test_problem.png A bead or beads (even dots) of paste (properties known) of given thickness and shap...

elmergrid and gmsh format
Hi Elmer team I am evaluating pointwise as a mesher for use with Elmer and there is a small bug which the pointwise gmsh mesh throws. In the latest version of gmsh the mesh format allows the following (from section 9.1 of the Gmsh documentation) "Any section with an unrecognized header is simpl...

Using Dakota optimisation software with Elmer
Hi All, I'm looking at trying to interface Elmer with Dakota https://dakota.sandia.gov/ and wondered if anyone else is using it who might be able to offer advice? I've already produced my own application that generates parameterized geometry using gmsh from a table of possible input parameters, mesh...

Re: noslip wall BC not respected (solved)
Hi All, After scouring the forum I discovered that I needed to put the following line in the Simulation section of my sif file. Set Dirichlet BCs by BC Numbering = Logical True I cannot understand why this isn't the default as otherwise (as I found) the BC's at shared edges e.g. in cfd an inlet and ...

noslip wall BC not respected
Elmer 8.2 Rev d3bf396 Windows mpi build Hi I have some 3D geometry built in Gmsh with a fluid volume with 2 rectangular inlets and 2 rectangular outlets. I put all the other fluid walls as noslip wall BC = True, the inlets have a uniform normal velocity applied, the outlets have zero pressure. When ...

Re: savescalars format
Hi Again, A similar problem is also the case for the mean temperature if you include Parallel Operator 1 = string sum, here you get the sum of the mean temperature of the surface in each partition and not weighted by the area of the surface in each partition ;-( I shall have to live with not using t...

Re: savescalars format
Hi Elmer team, When using save scalars with mpiexec & elmersolver_mpi and Parallel Reduce to get 1 output file then the following gives incorrect results in a thermal problem. Variable 1 = Temperature Operator 1 = "boundary min" UNLESS the boundary exists in all the partitions, if it d...

Elmer mesh quality
Hi Elmer team, Is there an Elmer tool that can determine the mesh quality of an Elmer mesh? I do my meshing with various tools (GID,Trelis,Comsol,GiD) and then export them in a convenient format then convert to Elmer format using Elmergrid. I am having convergence issues and NANs and wonder if it co...
