Re: Elmer workflow for electrical machine designers

Hello,
i would be interested in your tutorial, unfortunatly the links are all dead.

Could you update them?

best regards

Franz

Re: Elmerf90 - too big array (?) to compile module

Hi there, did you try to use the line continuation as peter sugested? as in CHARACTER TTL*16 REAL VEC(5), PAIR(2) ,VEC2(12) DATA TTL /'Arbitrary Titles'/, & M /9/, N /0/, & PAIR(1) /9.0/, & VEC /3*9.0, 0.1, 0.9/ & VEC2 /3*9.0, 0.1, 0.9, & 1.,1.,1.,1.,1.,1.& 3./ best regards Franz

Re: joule heating of material with anisotropic electric conducti

Ok, i think i found the problem, and its one for the Elmer team. But correct me if i am wrong, and i have been wrong before about details like that ;) So the way the Joule heat is implemented here, at some point the differentials.f90 module is active and there is the code part !---------------------...

Re: joule heating of material with anisotropic electric conducti

I also work with these solvers, thats why i am interestet in your problem. Just out of curiosity:
Are your boundaries the complete bottom and top surfaces? because, in the isotropic case, it looks like only the very corners have the (dark blue) 20 degree, and that they get hotter next to the corner.

Re: joule heating of material with anisotropic electric conducti

Correct me if i am wriong , but I did not see a "Heat Capacity" in your material section. You only have density and heat conductivity. I think this is essential for the heat solver.

Re: joule heating of material with anisotropic electric conducti

Hi there, what is the dimension (meters/millimeters) of your geometry? Often you don't see a change in some quantity when there is a scaling mistake. For example when you want the geometry to be in millimeters, but you got meters then the heat source is simply not big enough to cause a significant c...

Recompute Preconditioner

Hello Dear Elmer Team, i just wanted to try out the Linear System Precondition Recompute =Integer 20 feature of elmer. I have a solver with 2 dofs and a linear constraint matrix. Somehow the keyword causes no reaction at all. What i figured out myself, is that the solver%matrix%iluvalues are never a...

Dirichlet Condition in Code

Hi dear Elmer Community, So what i try to do is to implement a Dirichlet Condition from within a Solver by coding. The thing is that i have an automatic recognition of certain boundaries and now i want to switch on a dirchlet condition for some boundary elements. I dont want to give a separate bound...

Check if element is active in other solver

Hi there, i would like to perform some calculations in teh element assembly loop only if a certain element is active also in another solver. What would you think is the best way to check that? My first (very slow) solution would be something like otherSolver => GETOTHERSOLVER DO t1=1,GetNOfActive() ...

Oh Wow!
nice
that was fast!

i will check that out.

thanks peter!
