CFD Result Files - Convert plot3d(fast) > cgns

[minger]

Hello. I have a small problem. I have a CFD run going on our universities cluster. For those runs, I use a fully structured code that uses plot3d formatted files. Rather than have to go in there and look at them, I would like to look at them here at work, where we use CFX.

In short, is there a way to convert by grid and flow files into an appropriate file that can be read into CFX? Doing a quick google said that CGNS was a somewhat standard, so I figured that would be the easiest conversion rather than to an unformatted proprietary file format.

p.s. plot3d grid file is:

numBlocks
(imax,jmax,kmax,i=1,nBlocks)
DO i=1,nBlocks
  x(:,:,:),y(:,:,:),z(:,:,:)
END DO

and the flow file is similar

numBlocks
(imax,jmax,kmax,i=1,nBlocks)
DO i=1,nBlocks
  time,mach,reynolds,angle_of_attack
  mass(:,:,:),xmomen(:,:,:),ymomen(:,:,:),zmomen(:,:,:),energy(:,:,:)
END DO

Unfortunately, there is no universal format for CFD data and each software has their own proprietary format. You may be able to find some software that can convert the plot3d data into a format that CFX can read, but it could be difficult and time consuming. You may also need to use some custom scripting to do the conversion. Your best bet would be to see if your university cluster has CFX installed. If so, you can run the simulation using CFX on the cluster, which will ensure that the output files are in a format that CFX can read.
