Most variables in Elmer are per volume if it is 3D and per area if it is 2D, some are per mass.
the manual might specify
Electrostatics with volume charge

Re: Electrostatics with volume charge
Do you see a ring charge in the potential output? A blob of charge should change the potential distribution - a blob of dielectric not so much.
I don't see any change from the charge present vs the charge not preset. So I'm doing something wrong!
Edit: are there any examples that have charged particles or volumes added as "body force"? Maybe I should try that out.

Re: Electrostatics with volume charge
I see this
Re: Electrostatics with volume charge
Thanks, I will play with that. I dug into the StatElecSolve.F90 and it sure looks like this should have worked. Hopefully I'll figure out what I'm doing wrong soon!
Re: Electrostatics with volume charge
I dumped all the x, y, z points using a write statement, and copied that to a file. I then used those to feed into my formula, and realized I wasn't doing what I thought. I also found that paraview is "sticky" and I had to reset the amplitude scale every time I read in a new run. My playing around with amplitude was very confusing until I realized that. So now I get what I told it to do which is not what I wanted. But at least I can see what I expected:
I have a ways to go to understand how everything works, but at least I'm getting a clue.Re: Electrostatics with volume charge
Finally got what I wanted for the simple test.
Now I have a lot more to learn, but I think I'll pause while I'm happy.
