how to declare an array like: double Density_Grad_i[nDim]

Hi,

I'm trying to compile SU2V3 under win7@32 with MSVC2010express.

I have problem with numerics_direct_transition.cpp line 151 which is:

Code:

  double Density_Grad_i[nDim], Density_Grad_j[nDim], Conservative_Grad_i[nDim], Conservative_Grad_j[nDim];
  double Primitive_Grad_i[nDim], Primitive_Grad_j[nDim];

the compiler expected constant expression. So I changed it like this:

Code:

  double *Density_Grad_i, *Density_Grad_j;
  double *Conservative_Grad_i, *Conservative_Grad_j;
  double *Primitive_Grad_i,*Primitive_Grad_j;
  
  Density_Grad_i = new double [nDim];
  Density_Grad_j = new double [nDim]; 
  Conservative_Grad_i = new double [nDim];
  Conservative_Grad_j = new double [nDim];
  
  Primitive_Grad_i = new double [nDim];
  Primitive_Grad_j = new double [nDim];

and it passed.

And there are a few same situations in other cpp files.

After all the changes, I got an working su2_cfd.exe.

Hope it'll help.

Regards,

Cean

Great! And this was able to run a test case?
if you want you can submit a pull request to github and we'll try it out -
