Analysis of cold plate

Altair Forum User

Hello,

I am analysing coolant flow in a cold plate.

I have created 3 volumes namely

1. Fluid volume

2. Volume for cold plate so that in acusolve I will assign it a material

3. Heat source

I have applied boundary condition and applied material to volume 2 and fluid properties to volume 1.

but I am getting error in final processing.

please refer the attachment for the error file and the cold plate design for reference(blue colour is heat source)

Try to follow the workflow in Workshop1 from the video. Your setup would be similar.

In case it still does not run, please upload the .inp and .Log files here in the forum.

Thank you for your guidance. I have gone through the link you shared.

One more problem I am facing regarding the formation of bl. I have given the bl details in fluid domain only but I am getting in the solid also. Please check the attachment for ref.

I also checked my surface mesh allocation to fluid domain. It is also rightly organised. In the pic blue colour is fluid domain and pink is solid. In another pic please find the details for bl filled for fluid domain.

please suggest the possible cause of this error.

Having more BL elements than necessary is not a 'problem' for AcuSolve. It would just increase the calculation time and any ways, you require 3 elements in the solid part to have a good gradient in the solid temperature.

If you wish to really reduce the BLs in solid part, then while importing geometry (not mesh) into AcuConsole, use the option of 'Separate internal Faces'. This will result in two surfaces at the boundary of solid and fluid. Then appropriate settings can be used for meshing the solid and fluid volumes.

Thank you ydigit for the solution. I have successfully separated the fluid and solid surfaces and by using surface manager assigned the related surface.

Hello all,

in this analysis of cold plate . I have fins inside the fluid domain and outside the cold plate.

If inside and outside fins are treated as thermal shells in acusolve then in hypermesh the elements of fins will be in which collector: fluid collector or coldplate solid collector? As in pic you can see the placement of inside fins and outside fins. Blue colour is the fluid domain and grey colour is coldplate material
