Re: Emissivity as a function of another variable

Hi It seems that the code does not know that it will depend on temperature and at initialization temperature does not exist. You should give keyword: Update Gebhardt Factors = True Why are the factors needed before temperature is available? The Gebhardt factors need to be defined in order to know th...

Re: Whitney solver - Wire test case total current calculation

Hi The MATC thing might not be the issue. It is not needed here. It would be better to inform that it is missing only when needed but the parser does not check that. Still it is probably some installation thing. Can you run any *.grd file in the described manner? What is your OS and how did you obta...

Re: Speaker Resonator Interaction

Hi So this is the key point here: "Since the plate and resonator interact, I need a coupled system." This is not an easy task. There is one consistency test case for this "ShoeboxFsiHarmonicPlate". It basically creates a 2x2 block matrix for the coupled problem and solves it usin...

Re: Whitney solver - Wire test case total current calculation

Hi "Operator i" and "Variable i" are married. You can also define "Mask Name i" such that you can use different masks for different operators. The default mask name is "Save Scalars". Historically SaveScalars only operated on one geometric entity and then this...

Re: Electric machine stator deflection

Hi Observe that you should make sure that the solution for both stator and rotor is uniquely defined i.e. you supress the rigid body motion. This can be done with Dirichlet conditions as you do for rotor but I could not observe any for the stator. Spring constants could also do it. Small 2D case sho...

Re: change starting point, timesteps

Hi, If you are doing scan over frequency the benefit of good initial guess are next to nothing. The only place where the pseudo time (1,2,3,..) is seen is in the definition of Frequency. Why not have $t0=356.0 $df=1.0 Frequency = Variable "time" Real MATC "df*(tx+t0)" and play wi...

Re: Save Data on a Boundary

Hi SaveLine does this but whereas for 1D entities the result is a pretty line for 2D surfaces you have to make sense of the group of nodes yourself. So it might not be very helpful. In VtuOutput you have some flag to save only boundaries. That may be handy if that is all you are interested about. Sa...

Re: Unable to Start ElmerPost

Hi

ElmerPost is still in the source code but probably not compiled in any setups. So those who still want to use it have to compile it themselves. Paraview is quite a bit more versatile and basically the industry standard so keeping up with ElmerPost was futile.

Indeed, it was onnoyingly verbose. The info should now be present only at level 20. -Peter
