paraview cann't disaply vector from the results.

[ztdepztdep]

the output variables name are "Momentum x , MomentuyY",
it cann't be displayed as vector . how to resolve this.

[flexi-framework]

FLEXI stores each component of the momentum vector as separate, scalar array.
To combine them into a vector in ParaView, you can use a Calculator filter with the expression iHat*MomentumX + jHat*MomentumY.

i want to flexi ouput Veclocityx, velocityY directly. how to set the output control file.

[flexi-framework]

FLEXI outputs only the conservative variables, but allows to compute the primitives / derived quantities in the post-processing. As documented in the userguide section 4.6, simply add varName = VelocityX in the POSTI_VISU parameter file.
