The problem of liquid phase alpha value greater than 1 -- CFD Online Discussion Forums

qiuxian New Member Qiuxian Zhong Join Date: Apr 2022 Location: Guangzhou Posts: 4 Rep Power: 4	I used icoReactingMultiphaseInterFoam to use a laser to perform a simulation of melting and solidifying solid materials, but the calculation showed that the liquid phase alpha value reached 1.6 or higher. I have tried to reduce the maxAlphaCo and maxalphaDdt values in controlDict, and my time step is small enough. deltaT is 1e-8. I am new to OpenFOAM, can anyone please tell me how to solve this problem? Thanks!
