"No frame is defined for 0D applications"

Please login with a confirmed email address before reporting spam

Hello again.

I am trying to simulate an E-core transformer. When I click the study 1 and select the show default solver there is an error occurs "No frame is defined for 0D applications" . What is it mean?

Thanks

Asli

Hi

are you sure you selected "3D" or "2D" when starting your model ?

Good luck

Hello,

Yes, of course I'm sure I selected 3D . I don't understand why the program gives this error :(
When I changed the electrical circuit node's parameters (for example resistor, external I vs U. parameters (i.e p:3 n is empty) etc. ) this time program gives an another error such as "The DAE is structurally inconsistent. Variables:2 Equations:1 Error in automatic sequence generation"

I appreciate you can give me some suggestion

Regards

Hi

it's rue CIRis 0D "physics" so it's therein, you need to have a logical circuit without tangling items, check again your id numers, and note these re different (not linked) to the Terminal number id's

Hello Mr. Ivar,

What are the means of the terminal numbers and id numbers? Can you give me an example? I can not found the solution :(

My elecrical circuit (cir) parameters are:

Groung node 1: Connected to node 0

Voltage Source: p:1 n:0

External I Vs. U 1 : p:2 n:1

Resistor 1 : p:0 n:2

External I Vs. U 2 : p:3 n:0

Resistor 2: p:0 n:3

Hello,

I am having the exact same issue attempting to model an E-Core transformer. Has anyone found out what the problem was?

Were you using the time domain, as in the example model? I was also having this problem, and I discovered that switching from frequency domain to time domain fixed it.

Do you mean model in this site?
I had same problem.
First, I only solve with time dependent study.
It was solved. And then, I added coil calculation. It worked.

hello,I have the same problem,but I find the solution method .Maybe you circuit source is wrong ,and you can change it.
