Add correct error handling in svpre when creating a BCT file

[ktbolt]

A user is trying to performa a simulation of a coronary model. Selecting the Create Data Files for Simulation button and waiting a long time the Create data files has been created window is displayed with no errors. However, selecting the Show Details button on this window lists the following error message 260 times

ERROR:  Line does not intersect vtkPolyData!

Looking in the svpre source I see that this error message is written by a function doing something related to creating the BCT file (inlet velocity profile).

There are several functions called when when creating the BCT file and even though all of these functions return an error code (CV_OK or CV_ERROR) the returned error code is never checked.

I will add code to check for error conditions and add a message that could actually be useful to a user. An error condition needs to be propagated back to SV so it can notify the user that an error has occurred.

Hi @ktbolt ,
Any update on this issue as I am getting the same message when I try to create data files for simulation. The error occurs after SV starts to write the restart files. I loaded the geometry files (.stl) from external CAD source package and the segmentation was not done with SV segmentation routine.
