Failed to evaluate variable. - Variable: mwp.V0 1 - Global scope

Hello dear Comsoler,

dc.cir1.R1_i is something like in the dc module the current through R1 of circuit1...

I can somehow find out what the variable name is... but what when there is a space between the attributes?

like my mwp.V0 1 ? V0(space)1 and not V0_1 ? well this is an error message in the log window.

Warning: Problem encountered during results while solving.
Failed to evaluate variable.
- Variable: mwp.V0 1
- Global scope

does 1 stay for a domain ? a node ? a boundary or what ever?

who can tell me?.

I am struggling with electric circuits.. I have to feed a plasma model with voltage and current.. and as soon as the plasma is ready to be a serious plasma (when densities are created) my calculation stops because of lack of convergence.
My actual circuit does not like the increase in current due to the plasma formation..

Does somebody have a good circuit design for a proper "smoothened" power supply (a voltage source with sufficient current delivery capabilities)
and i am not sure it is because the current need is too fast that my model diverges or if i have to retain the current to artificially slow down the simulated physics ?

It is fun a while, but if no solution is in the pipeline.. it gets very rapidly frustrating.

debugging the model is a hard task.. i wish the tools for it would be more comfortable.

best regards from Nagoya
