problem of divergence

[Marcox]

Good evening, everyone!

My name is Marco and I'm working on my master's thesis.
I'm simulating ansys wb with a battery pack for autotraction.
the model consists of a case with cells inside. cooling takes place through a fan and vents located on the opposite side.

to begin I have simulated one cell, but there is nothing to do, the solution does not converge!

when I launch check houses tells me that it does not converge and gives me this error:
skewness exceeded 0.98 at 202 cells on thread id = 4.skewness exceeded 0.98 at 202 cells on thread id = 4.Does anyone have any idea what that means?

Sorry to bother you and thank you for your help.

search for the meaning of skewness in ansys' help ...:finger: .
represents the quality of the cell ...

Thank you so much for your help, I'm trying! :smile:

What kind of simulation are you doing?
thermal or cfd?

 

[Marcox]

I'm doing a cfd fluent simulation.

Well, I imagined it from the message!
you should post in forum di fluent!
However it is a mesh problem. you have very distorted elements (202 for accuracy).
