In electromagnetic simulations, what is the relationship with relative permeability and temperature obtained in the workpiece?

Hi, the tool to be heated is made of low carbon steel. It is heated by a few coils. Now, the relative permeability mu_r is 100 for low carbon steel. Now if I change the mu_r slightly high. I get a...

Comsol electromagnetic simulation. How to give a mesh for certain micrometer when my tool is in millimeter. The current density is so small. Pls help?

Hi, I am trying to perform mesh convergence and I found out there is no stable temperature value I obtained. So, I calculated the skin depth and it was around 0.00011mm. It is so small in...

HYPERMESH: Since I have performed structural optimization using hyper optistruct. Is it possible to do thermal optimization using Hyperworks ?

Hello, I was wondering if anyone has performed thermal optimization using hyperworks. As 99% of the performed demonstrations are just thermal analysis. I'm having a little struggle on finding my...

How to make the displacement value show up?

Hello all, I need a help really. I have displacement at a point as in the image where it shows Mag = 0 and Z = 0. Apart from static min and max. That nodal point on top I needed the values. Since...

How do I create a point away from my geometry and apply some force to it in hyperworks (hypermesh) ?

Can I create a Rbe2 or Rbe3 element far away from my geometry certainly like where I will apply a certain force to it. In short (Assuming there is a hanging mass). Can someone suggest.
