From Explicit to Implicit formulation
 
Hi,

I have a .cas and a .dat files in explicit formulation.

When I set from explicit to implicit formulation and iterate, then Fluent give me an error message.

Could anyone help me?

Thanks in advance.

Emanuele

Re: From Explicit to Implicit formulation
 
The explicit results are used as initial values for the implicit run, so what is the error message?

Hi,

this is the error message:

Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: ()

I don't know, maybe the inversion of the matrix to compute the solution is more complex in the implicit approach than in the explicit one. So I have this error from explicit to implicit and not from implicit to explicit. This is the only reason I can find.

Thank you
