### Re: About using Output Intervals

Thanks Peter,

From your example, is that means during the first 80 timestep interval, there is no output? And, the next 200 timestep interval, the output is saved every 2 timestep sizes of 0.5?

Thanks again,

Hello everyone, I have a question about using Output Intervals. Say, if I have a simulation with Timestep Intervals(2) = 180 Timestep Sizes(2) = 10 and I want the output for every 100 simulation time. How can I put this into the Output Intervals? I am slightly confuse on how to use Output Intervals....

### Re: Normal force in Linear Elastic Solver

Hi Peter,

Can you help me with the problem I asked about the "donut" model? Any suggestion would be appreciated.

Best regards,

### Re: Normal force in Linear Elastic Solver

One more question:

Is it necessary to write the Coordinate System String to Cartesian 2D in solving 2D simulation? How to change this in the ELMER GUI (or is it automatically recognised as 2D depending on the geometry used?)?

### Re: Normal force in Linear Elastic Solver

Thanks Peter, I tried to run a simple simulation by using a coupling of heat equation and linear elastic solver. I have a "donut" shape geometry shown in the figure below. I want to apply a normal force at the inner boundary, so that the displacement at the boundary can be free. This norma...

### Normal force in Linear Elastic Solver

Hello everyone, I just want to ask regarding the normal force for boundary condition in linear elastic solver. What is the unit of this force if assuming the SI units of all variables i.e. stress is in Pascal. Is this force is in unit Newton (N) or in other units such as N/m (force per unit length) ...

### Re: Using Strain as variable for a user define function

Hello all, It seems that my post has no reply from anyone. I will try to explain my problem simpler as given in the attachment below: I want to create a user define function to calculate the concentration changes, but how can I calculate the trace of strain? Can anybody give some idea? My idea so fa...

### Using Strain as variable for a user define function

Hello everyone, I have a problem which requires the use of the trace of strain, E (which is used to find the volume changes) in a user define function that calculate the change of concentration within a solid material. Can you guys give some idea on how can I determine the Tr(E) and use it in a user...

### Re: Poroelastic Modelling

Hi Peter, It took me quite awhile to try the method that has been discussed in this post. I just want to ask, if I name the variable temperature in the solver section below: Variable = Temperature as something else, say TempA, will I need to make some changes in the solver as well, ie the .F90 code?...
