Creating Chimera Grid in Gridgen
I am new in Gridgen and I got a problem with overset Grid aka. Chimera, do somebody here know how to create overlapping grid and make a hole cutting using Gridgen? (as example using hole cutter Pegasus or Suggar). If somebody here know what to do, please help me to solve this problem. Please see my Grid on the attachment.
Thank you in advance!
As you've already done, Gridgen (and Pointwise I might add) can create the overlapping grid. It does not have however have any hole cutting ability. It does however interface with Pegasus and Suggar, meaning it can create the input deck along with the grid files that are provided to either hole cutter as input.
You will need to obtain either Pegasus or Suggar (through their respective owner) to actually perform the cutting.
Additionally, once the mesh has been cut, Gridgen can then read in the overset information from the hole cutting step and display the cut mesh along with fringe and orphan points. There's a specific set of examine functionality dedicated to interrogation of the overset information.
Hope that helps.
Thank you so much!
So that's why I can't make a hole cutting using Gridgen or Pointwise. I have also heard that hole cutting could be done by using FlowEr software from DLR (Germany), Maybe I will try to figure out using this software (since I am not US citizen, so I can't use Pegasus, isn't it?). Or, maybe if you have some experience using FlowEr, please let me know related to this issue.
