Save Strain/Stress data
Hi, I'm trying to save one component of stress or strain tensor in particular point with SaveScalar subroutine. This is possible? the code below works fine to save scalar fields like temperature or even time but i'm not lucky to save tensor components like stress or strain. Solver 2 Procedure = &quo...

Re: Non-Uniform Stress Distribution along curved surface
Hi, See Elmer Solver Manual chapter II, the section is called boundary condition, basically: Boundary Condition 1 Target Boundaries(1) = 1 ! 1 is the number of surface (for 3d problem) or line (2d problem) Name = "non-uniform stress distribution" Normal Force = Varible Coordinate; Real MAT...

Re: Non-Uniform Stress Distribution along curved surface
Hi, Yes, it is necessary place axial coordinate in the center of the hole, only for the expression previously mentioned. If the hole position is not centered, you need to write the stress distribution as a function of your system reference x-y-z, wich can be more o less difficult depending on the ge...

Re: Non-Uniform Stress Distribution along curved surface
Hi, You need to use a MATC language to define this boundary condition. The easy way is defining a normal stress like a bondary condition. The sif file should look as follows: Boundary Condition 1 Target Boundaries(1) = 1 ! 1 is the number of surface (for 3d problem) or line (2d problem) Name = "...

About restart from existing solution
Hi, i'm trying unsuccessfully to use the restar command. Here is the question, i have one model, a thermal model that solves the temperature field. In the other hand, i wanna solve thermal stress generate by the temperature field previously calculate in the first model in a specfic time step. Accord...

Introducing components in a tensor with MATC
Hi, i have a question, it is posible introduce a tensor with a MATC function? For example, defining a tensor where each component is written in MATC.
Thanks in advance.

Difference between poisson ratio and mesh poisson ratio
hi, i'm running a termomechanical model and i have a question about the difference between Poisson ratio and mesh Poisson ratio. I known the Poisson ratio (denoted v or nu) but i'm not sure if it has any relationship with mesh Poisson ratio.
Thanks in advance.

Re: Time-dependent sink/source term
Apparently, the correct way to define a parameter that depends on time and coodinate system is Parameter = Variable Coordinate, Time ; Real MATC "function(tx(0),tx(1),tx(2),tx(3))" Where tx(0), tx(1) and tx(2) are x,y and z respectively and tx(3) is time. It's important matain the order to...
