外围体育投注My University has an HPC but I haven't found out how to get the HPC to run my CFX design points.


It can run workbench files but won't touch my design points. Does anybody know how to get the HPC to touch design points?


It uses a workbench wbjn file to complete the run:

"Open(FilePath="/scratch/[username]/hprun.wbpj")

Update()

外围体育投注Save(FilePath="/scratch/[username]/hprun.wbpj", Overwrite=True)"

外围体育投注I have a structural model where grubs screws (bolts) are to be tightened up in compression against a plate to provide shear resistance to it. I need to apply a designated precompression force. Does anyone have a recommendation on the best way to apply this precompression and then lock it. It is simple to do with pre tension cases as can use pre-tension load but nothing like this is available for bolt compression.

Well.. I have almost the same problem another user had 2 years ago and got no responses... so I will repost the question. My case is a nut in a pedicular screw as you can see here:

Thanks in advance.

Currently, I am a student in the 5th semester of Mechanical Engg. in India. I want to pursue as a design/CFD/FEA engineer. what are the career opportunities in this field? what are the requirements to work in a reputable organization? and what is the salary range in this field for India as well as foreign countries?

Hello,

I am trying to write a named expression in Fluent that changes the cell zone volumetric heat source term (W/m^3) over time.

外围体育投注The logic of the source term is split into 4 sections:

外围体育投注Time of 0 to 100 seconds, source term should be 150,000 W/m3.

外围体育投注Time of 101 to 250 seconds the source term should be increased to 230,000 W/m3,

外围体育投注Time of 251 to 500 seconds the source term increases again to 350,000 W/m3,

外围体育投注Time of 501 to 750 seconds the source term 450,000 W/m3

外围体育投注Time of 751 to 1250 seconds the source term should be 525,00 W/m3

I played around and it may work out to this statement here:

IF(t<=100[s], 150000 [W/m^3], IF(101[s]<=t<=250[s], 230000 [W/m^3], IF(251[s]<=t<=500[s], 350000 [W/m^3], IF(501[s]<=t<=750[s], 450000 [W/m^3], IF(t>=751[s], 525000 [W/m^3], 0[W/m^3])))))

外围体育投注How to define (assign) temperature to a wall or cell zone part?

外围体育投注I thought it have thermal option open, but its not applicable.

I've been trying to do topology optimization but every time I run solve I get an error that says "The execution of the optimization solver was not successful. Please verify the install." How do I fix this? Thanks.
