Incredible work and very hepful! Congrats! Can I ask a question, how does parallel processors affect solution speed? For example my computer has 16 logical processors so i chose 4 parallel processors in the set up. I see in the task manager that when i chose 4 parallel processors during solving it opens 4 processes. So in reality i choose processes or logical processors? Meaning i can choose more than 16 processors? Thanks in advance

Hey, you have got the same result for each of those input parameter design point. I guess you should be able to get some change in result if your simulation is working properly. Did you figure out what has not been accurate in such case? Your opinion would be highly appreciated.

You need not select "keep this settings for all future calculations" while closing the fluent.

Thank you so much for your help. I am confused, if I have set the iterate times as 1000, if I change the boundary values parameter setting and update， will each case run 1000 time？In these， you do not change the diameter， if I set the diameter as a parameter, can it work? Finally, what is your goal at last, I do not know which is the optimization values at last?

@AnsysTutor 4 жыл бұрын

Yes for each parameter case it will iterate 1000 times. For geometry change also it will work similarly. The aim of parametric method is to save the setup time for each case. If you want optimization you need to analyse the desired result .

What is the meaning of 'add frozen' in the design modeler and why did you use it after generating the body?

@AnsysTutor 3 жыл бұрын

Add frozen option makes the body separate from the previous created body. It keeps them as a different part. Whereas "Add material' option joins the new geometry with the previous one.

Late to the party, thank you for the video. I have a question. Can I monitor the residual or any value of interest during the parametric study? I am blinded during the whole process and don't know if my case actually converges.

@AnsysTutor 2 жыл бұрын

In parametric study we cant monior the residuals, however the residuals vs iteration plot would be similar in all the different parameters.

Thank you very much for the tutorial, it helps a lot. I have a question, in this tutorial we have created parameters for inlet velocity, inlet temperature, outlet temperature etc. but what about designing dimensions of our model? For example can we similarly create parameters for diameter of the cold inlets and after post processing, we change the value of diameters and operate analysis with these values? Thanks in advance.

@AnsysTutor 3 жыл бұрын

Yes you can also vary the geometry using parametric , to know the detail procedure watch out tutorial on critical thickness of insulation, here is the link kzfaq.info/get/bejne/icmXY5iSmd-2YYk.html

Thanks for the tutorial. It's very good but I have a problem that my new design point outlets, won't update to the new input value. They remain the same as the original DP. I have checked that the setup uses an input parameter and in CFD post I have made the outlets, out put parameter. Any ideas where to look for the problem? thanks again

@AnsysTutor 5 жыл бұрын

there might be a change in some decimal places, so try to increase the decimal places, try with some different parameters and check.

It will keep writing the result data if you select retain option. If you will not select that, you might lose the results data obtained.

@muhammadshariqkhan4498 3 жыл бұрын

Hi sir i have a really important question. I got ur point that it saves case setup time. but lets say i run for 7000 iterations, and iterations took 8 hours and then I varied lets say mass flow rate 10 times in parametric study. it will re-iterate to give us results in parametric table so wouldn't it require a huge amount of time to run 7000 10 times. how much time it takes usually? will it take the same 8hrs+8+8+8+8+8+8+8+8+8 =80 hrs,? or it will take less time than first iterations? also one more thing, we encounter situations where when we change input BC lets say in my case flowrate, it diverges or confronts reverse flow, wouldn't it stop the result? or the parametric study will give results whatsoever?

@AnsysTutor 3 жыл бұрын

Yes, it would take that 80 hours of time. It only saves the time of the user for the BC setup each time. If you don't have any divergence it would not stop even though it's a reverse flow warning.

Thanks for this tutorial. I have a question concerning the initialization in a parametric study... In the case of simulating VOF, the other phase is defined by patching the zone in the initialization, However, for the parametric study I don't know how to patch and initialize

@AnsysTutor 4 жыл бұрын

i guess, Patching might not work with parametric setup. You might need a UDF for that.

@ShamJam85 4 жыл бұрын

you directly updated a specific design point for getting output velocity, does not it require re-iteration at every new design point?

@AnsysTutor 4 жыл бұрын

only you need to iterate once ,and save , while saving it will ask "save the setting for current & future calculation" , only these no of iterations will be repeated in each design points. Only difference is you dont need to open the fluent again & again , the parametric setup will load the mesh , will put the BCs and will iterate itself.
