the combustion model problem
 

Hi,
I want to simulate a diesel sector with the EBU-LATCT+Shell Ignition model. Then I get the sector in prostar from es-ice and change the combustion model. But when I compute the simulation, the combustion model is still the CFM model which is the default choice in es-ice. I think the 'save_ice_after_map' file may contain the CFM information.
So how can I replace CFM model with the EBU-LATCT+Shell Ignition model successfully?
Thank you.

Maybe you can give up to using the starcontrols after starsetup.

Hi skylent
I have got your opinion. But the file 'save_ice_after_map' is needed to perform the simulation, which comes from the star controls? How do I deal with this problem?
thank you.

when you operate the"star setup" process, remember to deselect the "use star controls" option, and then you can set the initial condition, boundary condition,combustion model,time step... in prostar.

I also met the same kind of problem,I select ECFM-3Z SI model in "star controls", and the fuel I selected is methane(CH4). However, in prostar, when I check the combustion model, the default fuel identifier for laminar flame speed is isooctane, and after I change it to methane and save the model, the fuel identifier become isooctane again when I reopen the model. It troubles me so much.

Hi skylent
I follow your steps, deselect the "star controls" option in the "star setup" panel. But the mistake appeears," The file "save_ice" does not contain the image of an Ice save file.//Error reading from the save file.//Failed.". I think it's about the file Ice. But after I copy this file to my dictionary, the mistake does not change. I'm very confused, expect to get your reply.
Thank you.

I'm sorry for that, but when I use Map method and trim method, it didnot have these problem.

Hi skylent
Thank you all the same. I think I must get another way to solve this problem.
Best regards.

Change the Extrusion ratio to -1(not extrude for boundary layer)，and remake the mesh.

Because I found these sentence in es-ice userguide:"This new surface will have a one-to-one correspondence with the old boundary surface and its vertices will not be positioned at the correct location. During Star setup with the selected Use Star controls option, the extruded faces will be moved to the correct location."
