Elmer Discussion Forum

The two meshes are identical for CalculiX and Elmer. In CalculiX I used the c3d8i that are special elements in which shear locking is removed and volumetric locking is reduced. I'll try benchmarking with other elements formulation like c3d8 or c3d8r (normal hexahedral and hexa with reduced integrati...

it is the first time I used the eigenfrequencies modules of Elmer. I'll ask two question: 1) are the last output in the dos shell the eigenfrequencies w^2? (have a look to the attached image) 2) there is a method to writes them in a files? The comparison between the eigenfrequencies computed to Calc...

ok, the unlisted keyword doesn't matter. In the attached zip file the same philosophy but on a simplified mesh. I would like to simulate a thermic analisys that involve an heat exchange between an internal core (heated by a volumetric source, via Body Force 1 ) to an external cover but without simul...

hi all, in a thermic simulation I will use a target variable as an input value. In the save scalars section I define: Solver 4 Equation = SaveScalars Procedure = File "SaveData" "SaveScalars" Exec Solver = after timestep Filename = Tint.dat Variable 1 = Temperature Operator 1 = b...

ok, also for volume computation I could use the same save scalars with the operator "volume".
But this is the total volume of my model.
Is it possible to perform computation on different bodies in order to obtain the mass for the different materials used?

ok, I found the solution for the boundaries area via the save scalars procedure with the operator "area".

But for the mass compuatation for different bodies I still need help.

Bye

I would like to know how is possible to have a summery information about the fem model. In my specific case I need to know the mass of every different body in an axialsimmetric mesh model. Moreover is it also possible to know the suerface areas of the different boundaries? Many thanks in advance, ALex

Hi all, may be I did some errors but I can not understaind my results. On some bouldaries I impose an adiabatic condition like: Boundary Condition 8 Target Boundaries = 19 Name = IntConveMidi Heat Flux BC = True Heat Flux = 0 Save Scalars = Logical True End but if I check the outgoing convective flu...

may be I found the mistake:

I have to initialize the variables:

$ TintMidi = Tamb
$ Tintmini = Tamb

an then add the:

Update Exported Variables = Logical True

to the save scalars procedure!

Hi all, I found some trouble in save scalars procedur. What I need is to set an External Temperature as an internal variable taken by the save scalar procedur. My code is: ...omissis... Solver 4 Equation = SaveScalars Procedure = File "SaveData" "SaveScalars" Exec Solver = after ...
