Re: Speaker Resonator Interaction

Many things to discuss on elastic deformations. The SMITC solver is for 2D elements not solid elements. If model with plate elements (2D elements with thickness defined for out of plane deflection) then the shell solver is more suited. 3D elements would require elasticsolver 3D elements. Attached is...

Re: Whitney solver - Wire test case total current calculation

The first format of the command is correct
ElmerGrid 1 2 wire.grd

but this result is not good
Unable to activate matc as it is not even compiled.

Sounds like an installation issue

Re: Electric machine stator deflection

Without seeing the mesh and boundary conditions it is difficult to determine why convergence is slow, you could increase the maximum number of iterations. You may want to read through these posts for convergence strategies with linear elastic http://www.elmerfem.org/forum/viewtopic.php?p=26972&h...

Re: Speaker Resonator Interaction

The first error I received was unrecognized keyword Spring changed it to Spring = Real 1.471E+03 Second error was the helmholtz solver could not find frequency added frequency to solver 1 Frequency = 5000.0 Third error was it could not find youngs modulus, poisson ration, thickness for the plate sol...

Re: change starting point, timesteps

See elmersolver manual chapter 3
https://www.nic.funet.fi/pub/sci/physic ... Manual.pdf

you would have had to ask for a restart file to be written in the first run, it is not done by default.

Re: Laser absorption in lens and thermo-elastic analysis

and if instead of body force you wanted to specify a temperature for each node then instead of a body force load you would write a boundary condition to target a node or nodes such as Boundary Condition 3 Name = "Target Nodes" Target Nodes(4) = 895 897 899 901 Temperature = 350.0 End Examp...
