Hi have you tried the laserconvectionBC from tobais? I cant seem to get it to work.

Im running OFv2006.

Which version did you run it on?

How do I adapt it to latest OFv2006?

Hi Gentodin,

Yes, I used the laserconvectionBC for OpenFoam-v1812 so I'm pretty sure it will work for v2006.

I would need more details of your problem to help. One common error is forgetting to include "libs ( "liblaserConvectionBC.so" );" at the end of your controlDict file. Other than that, I don't know if I can help any more than the readme file that comes with the laserConvectionBC file.

Hope that helps!

Hi OPFO,

I manage to get it to work with v1912.

Also, are you familiar with the solver icoreactingmultiphaseInterFoAM, I wanted to edit the files for my solid and liquid thermoproperties but could not find any guide to the symbols used.

Do you know?

Good day. I was trying to use icoReact... solver and it does not work, thus i have many questions. What kind of boundary conditions should be applied to the irradiation surface? What kind of solvers did you use? Can you please share your case files for better understanding?

Hello,everyone!

Does anyone know how to stop the scanning laser irradiation?

When the scanning laser reaches the end point, the laser irradiation does not stop, and it seems that the irradiation continues at the end point.

I want to know how to stop the irradiation when the scanning laser reaches the end point.

Someone please give me some advice!

Hey Gentodin,


you don't happen to have found a way to get the BC work in OpenFOAM-v2006, do you? Working on a Cluster I only have access to the v2006 version and I can't seem to get the "wmake libso" function to compile it properly due to the changed syntax used..

Greetings,
Jon

Hi, are you find any solution for marangoni effect?

I myself was able to model the laser, however there some implications:
i) it is a volumetric heat source and depending on your application may not be proper to use.
ii) the heat source is not applied on the exact position center that you define, but a little further. and it is applied from that position all the way downward to the end of the domain. By the way you can modify this penetration depth by manipulatng the code. that's why in the dictionary I have also define an extra opd parameter.
I am not sure if I am using the laser property in a wrong way or not. if you find solutions please post them here.

I happen to use the same Radiation properties file that you have put up here for the IcoReactingMultiphaseEulerFoam solver. But the file exits saying

"Current functionality limited to 3-D cases" from the laserDTRM.C file line 234 where it checks "if (mesh_.nGeometricD() == 3)".


I tried to print out what this function "mesh.nGeometricD()" returns. I returns 2. I know it has something to do with valid directions. Please let me know why I face this particular issue.



Regards,
Harris.

Hi ahomaru,


I developed a Marangoni convection model on a solver based on earlier version of interFoam. I could probably offer some help. But now I am looking forward to upgrade my model using icoReactingMultiPhaseInterFoam. Does this solver allow you to have metal and gas phase? I tried to change the standard solidMelting2D test case to include gas phase aswell but I was't succesfful so I wanted to know if you have included gas phase or not. Or if you know if it is possible to modify the tutorial case solidMelting2D to include gas phase?


Best regards,

[Harris_Daniel]

Best regards,

This icoReactingMultiPhaseInterFoam is a multi-phase solver that includes more than 2 phases. Marangoni convection can be introduced if you want to do so. Metal solids can also be included.

Hello Madeinspace,

i am still working on the implementation of the marangoni convection in icoReactingMultiphaseInterFoam. Maybe you could look into my Code and Testcase Setup.

Hi Schmidtgen


Sure. Have you uploaded it on the forum?


Br,

[Schmidtgen]

Not yet. I'll upload it soon.

[Schmidtgen]

Here is a version of my Solver and Testcase. The Testcase is discussed in

Tan, L.H., Leong, S.S., Leonardi, E., Barber, T.J., 2006. A numerical study of solid-liquid phase change with Marangoni effects using a
multiphase approach. Progress in Computational Fluid Dynamics, 6, 304-313

You can't use laserDTRM with buoyantSimpleFoam. It only works with icoReactingMultiphaseInterFoam.
The valid radiation models for buoyantSimpleFoam are printed in the error message.

and the corresponding closing bracket.
