Earth Rescue reveals what visionary companies are doing today to engineer radical new ideas in the fight against climate change. (My model is so that I can replace HDSP load by inserting 2 conventional pressures at surfaces (one positive, one negative) but it is not as conventient. But so is the human ingenuity to fight it. If you have a certain part defined as an. Any ideas Unselect the entities, and then use PLDISP command. I have been searching for some time on how to do this, but without success. But if they are as they are presented above, the results are compelety bizarre.ġ) Can I use IC & BF to define hydrostatic pressure and temperature, respectively, at the same time?Ģ) Both commands do not work unless 'Large deflections' are activated in Static Structural. I am using an APDL command in Mechanical to save images of the mode shapes in a modal analysis, and I would like to hide some of the bodies in the PLDISP output. If IC command is before BF command, then BF is neglected. I have an analytical method to validate it. Similarly, if change HDSP=0.001 and keep BF=20 (body load 0) the model works correctly.īut, If I change both of them, the results are not correct. When I change BF=30 (body load 10) and keep HDSP=0 the model works correctly.

Now when the BF=20 and HDSP=0, nothing happens, naturally. TREF,20 !Defines the reference temperature for thermal strain calculations.īF,newnode,TEMP,20 !Assign a temperature to pressure node TOFFST,273.15 !Specifies the temperature offset from absolute zero to zero. TBDATA,1,1.7e-9 !Density of the gas kg/mm3 I use this APDL command just prior the Ansys Solve command: I want to add temperature and pressure to the node 'Q' of the HSFLD242 element. I am using HSFLD242 element in Mechanical.
