[SOLVED] [CST] Time domain solver does not support mesh size

[kamiar.t]

hi
i have a problem in my CST simulating CPW-fed antenna ,it's urgent
the error "Time domain solver does not support mesh size > 2 billion mesh cells in case of:
- 32bit Windows FrontEnd
Simulation cannot be started."

regards

I think it's a problem of simulation setup, because 2 billion mesh cells for an antenna is quite a lot. You don't need so much, and if you were able to simulate, you'll have a lot of free time.

but the simulation will be stoped because of that error.
what can i do?

Reduce the number of mesh cells. Start with a low value and use adaptive meshing.

I did.
but it doesn't work,
the same error will appear :sad:

Can you upload your project file?

thanks alot

You have a trivial but important mistake in your model: the units are set to meters so that your antenna size is some meters. This is obviously wrong, and leads to extremely large mesh size. Correct the units and you should have a reasonable mesh.
