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...
