Hi,
Can anybody tell me details about how to use Constant Anisotropic 3x3 array for Conductivity in Acusolve
Best place to look is in the AcuSolve Command Reference Manual - included in the 'Help' system of the distribution. It will be in 'Material Model Commands' > CONDUCTIVITY_MODEL. From this: "The elements of the anisotropic conductivity tensor are always specified in the order k11, k22, k33, k12, k23, k31." Thus, for a material aligned with the X/Y/Z coordinate system, the first entry k11 is the X-direction conductivity, the second k22 is the Y-direction, and the third k33 is the Z-direction. If the body is not aligned, you will need to perform the appropriate tensor transform.
Thanks for the reply, i am clear with k11,k22,k33 , but not clear with k12,k23,k31 if possible can you share any examples
Those off-diagonal terms are for anisotropic materials. The general heat transfer equation is:
