Hi,
I have been trying to simulate the powder bed formation, but then after simulating, the alpha.liquid file values show the liquid particle size is of the order 10^-300. I can't visualize the liquid particles or melt pool because of the small size.
The solver I used is icoReactingMultiphaseInterFoam.

Can anyone please tell me what and where the changes I should do to increase the liquid-size particles?


These are some of the values in alpha.liquid in final time step,
3.17614e-308
7.7113e-304
1.32982e-299
1.57047e-295
1.15305e-291
4.01975e-288
3.73562e-287
1.07187e-283
1.14778e-279
7.98268e-276
