Greetings,
I am doing a simulation in which I need to create several solids with orthotropic properties. I've searched on these great CFD Online forums, but haven't been able to find a solution that works entirely. I have confirmed that CFX is interpreting my CEL correctly through the output file for the X, Y, and Z axes. The snippet looks like this: THERMAL CONDUCTIVITY: Option = Orthotropic Cartesian Components Thermal Conductivity X Component = .8 [W m^-1 K^-1] Thermal Conductivity Y Component = 144.75 [W m^-1 K^-1] Thermal Conductivity Z Component = 144.75 [W m^-1 K^-1] END I also suppress the GUI errors pertaining to these in order to get the simulation to run, which runs just fine. The problem is that I have created a simplified ANSYS Workbench model to validate the CFX approach, but the results do not match with all variables the same. I believe what might be the culprit is XY, XZ, and YZ values of thermal conductivities that are being set to zero in the simulation (you can do a contour of these in CFX post). Has anyone else encountered this, or know who to set the off axes properties? I've been working with a CFX consulting group and they are going to ping ANSYS to get some answers, but I was wondering if anyone knew anything in the meantime. I'll let everyone know what I find out since this topics appears to come up a lot. Thanks in advance for any insight. Cheers, Mark |

Can You send a drawing of this problem with thermal conductivity on each side which you want to define ?
Best regards |

After more debugging and speaking with ANSYS, it appears that the orthotropic properties are behaving correctly. The problem appears to be with a solid to solid domain interface in CFX. Essentially, there is a large temperature rise across the interface that should not be present. I will try to upload some picture later tonight. Cheers, Mark |
