Hello everyone,

I have trouble initializing a case using a previous result when I try to run a simul...

Hi everyone,

It seems to me that the field bounding limits are only applied in stationary simulations, and not in transient simulations. Indeed, in one of my transient tests, many cells of my domain reach values (the velocity in my case) well above the max velocity indicated in SIMULATION/Controls.

Are you aware of this comportment ?

Thanks in advance !

Hello everyone,

I have some questions regarding case initialization:

1) In steady-state simulations, I assume that the conditions defined in the "Initial Conditions" section are only used to initialize the first point of each speedline, and that subsequent points are then initialized from the previously calculated point in the speedline. Is that correct?

2) In transient cas...

Hi everyone,

In the latest version of TCAE (25.03v1), it is possible to set new parameters in the SIMULATION/Controls section: the solver max and min iterations (photo attached). What exactly do these iterations correspond to?

Thanks in advance.

Hello everybody,

I have a few questions regarding TCAE transient simulations.

Hi everyone,

I have a question concerning the mixing plane interface method : it seems to me that the method can generate numerical errors when reverse flow occurs on the interface.

To be more specific, I have a radial interface between the outlet of a centrifugal impeller and the inlet of its diffuser. On a specific zone of the interface, reverse flow occurs w...

Hi everyone,

I woud like to export the relative velocity URel magnitude, instead of the absolute velocity U magnitude, in the interfaces files created by TCAE in ../stationnary/postProcessing/interfaceName/0/interfaces.csv. I tried to change the file ./stationnary/system/interfaces. fun by replacing magU by magURel in the list of fields per interface but it did'nt...

Hello everyone,


I have questions about the calculation of circumferential angles circA by TCAE.


I have understood that, if a surface is oriented in the radial direction, circA on this surface will be the angle between the tangent and the velocity in the radial/tangential plane. According to graphical representation of the manual, circA shoud be positiv when the...

Hi everyone !

It's my first post here and I have a few questions on post-processing's manipulations and on variables' meaning :

1) How can I get the surface areas of the components' interfaces on TCAE (Paraview interface) or in the calculation case's folders ?

2) The TCAE user manual indicate that here are 2cir...
