can i export results from Hyperworks-cfd to excel?     I want to export steady state results for convection coefficent and Temperature for each node on the surface boundaries.

 

can i hide individual surfaces in Post processing?  The surfaces that are separate in the Geometry tab are combined all together in "default wall" (based on the boundary conditions) and it is hard to hide a surface to see the results behind it.

 

thanks

    If you have activated Surface Nodal Ouput on your desired surface, you may be able to use the 'Convert' tool in the 'Solution' ribbon to get some of your data.  Output format is Table, Data Type is Surface Output (Nodal).  Then select the variables you wish to convert.

    You may also try acuGetNodeSubset from command-line, like:

    acuGetNodeSubset -pb test -osis "Wall_Surf" -outv temperature,surface_film_coefficient,heat_flux

    This should give you a file with x/y/z coordinates, temperature, surface_film_coefficient, and heat_flux for the nodes on "Wall_Surf" (a surface with Integrated Output active).  You will also need Nodal Output active on that surface in order to get the heat_flux variable.  You'll probably want those in order to define the convection coefficient using a manner consistent with other definitions - as surface_film_coefficient is defined purely from the turbulent flow.

    If you look in the Post model tree, your initial 'Boundary Collections' object is populated based on the defined Flow Boundaries - so those boundaries can only be displayed/hidden based on those sets.  For additional flexibility in displaying/hiding surfaces, you can create a new Boundary Collection: right-click 'Boundary Collections' and select 'Create'.  This creates a new Collection, with all surfaces in one set.  Now you can create additional sets based on boundary sets, surface outputs - or by manual selection - then you have the ability to display/hide based on sets you create.  Note that the surfaces available for selection may still have some relationship to how they were originally grouped.  But if they were in AutoWall and not put into separate BC sets, they should have more flexibility in selection.  Note also that only one Boundary Collection is active at a time.  I'll attach a short recording of this.
