FSI Transient Load Mapping ACT extension: imports transient pressure and temperature profiles in ANSYS Mechanical for 1-way FSI. (Coupling Transient CFD with Transient Mechanical). One doesn't need to go for System Coupling module.

But imported pressure is gauge pressure computed in FLUENT. Talking about System Coupling, in documentation it is advised to set such value of reference pressure in FLUENT that exported pressure results in actual system pressure while coupling. (Submerged pipe example is given in documentation)




In my case, using ACT extension, i've set desired reference pressure and it was expected to behave same but it's still exporting gauge pressure instead of actual system pressure (gauge + reference). May be, i didn't expect it right or my methodology is wrong. Can someone guide me please.

To those, who'll be looking for it's solution.

If Absolute Pressure is already in exported variables list, just change the 'Pressure' to 'Absolute Pressure' in CFD Post Macro you got with this ACT Extension.

In my case, it was not present. I just defined a variable representing absolute pressure (gauge + reference) and put that in cfd-post macro.
