There are three test cases named levelset

This function returns an error if there is insufficient buffer space. The amount of available buffer space is controlled by the user by using the MPI_Buffer_attach function.

MPI_BUFFER_ATTACH(BUFFER, SIZE, IERROR)
<type> BUFFER(*)
INTEGER SIZE, IERROR

The intent is that the nodes are coincident and you are using conforming to glue them together. They do not have be to coincident but then you need to define the mortar conditions so that the non-conforming mesh nodes can be determined for the mortared boundary. It is not intended to be used as in y...

The best approach is to name everything in gmsh, bodies, and boundaries. The default in gmsh is to only save named entities, if you use names. This gives the most control over what becomes what in elmer. The easiest way to do this is in the gmsh gui. You can name the boundary, select the lines that ...

gmshe.png Your geometry in gmsh is 2d you have a surface and lines in 2d the surface becomes a body in elmer and the lines become boundaries in 3D volumes become bodies and surfaces become boundaries in your geo you name a volume 2 but there are no volumes present. you name a surface box1boundary b...

I have not seen this before and do not know what the result would be; Relative Permeability = Procedure "TestLib" "MyFunc" What I have seen, used, and is in the manual is Relative Permeability = Variable SomeVariableinTheSimulation Real Procedure "TestLib" "MyFunc&...

OK I fixed that.

Can you attach the complete sif file and the complete function file?

I believe the linear/non linear convergence tolerance of a solver applies to that individual solver. Each individual solver stops when it converges. Then the next solver starts. The steady state convergence applies to the equation which is the combination of all the solvers A common stopping criteri...

the call has to match the name and the list order. In the calling code returnval = myfunction(val1,val2,val3) in the function being called it has to be named the same myfunction(s1,s2,s3) return s1*s2*s3 and therefore s1 =val1, s2 = val2, s3=val3) and returnval = s1*s2*s3 the local variable names in...
