Hello,
i want to run one study in which i have different types of steps.
First a stationary to solve a flow, afterwards solving a time-dependent to solfe a heat transfer simulation for some seconds, afterwards solving a flow again.
With activated pseudo-time-stepping, a generate the error:
Undefined variable. - Variable: CFLCMP
When i disable this option, i can run the first stationary and the first time dependent study. But when the second stationary study starts, i receive the error message:
Undefined variable. - Variable: timestep
Even when i force the equation of the flow to be in the stationary form.
I don´t get this error. Shouldn´t there be the same calculations like in step 1? In both steps, the multiphysic non-isothermal flow is activated, the solver settings are the same...
Has anyone an idea why this problem occurs, or a guess how to solve my problem?
I have a really simple test file, which needs about 2 min to run, where the problem is shown.
Thanks,
Henrik
