    how to solve this negative eigen value error?

    I have given all the boundary condition right. but still can you please check it once here I attached file. The only problem is that glass doesnt move in next step. Even I have started early to move glass before filament touch to it but still it wont work...

    how to solve this negative eigen value error?

    So what can I do? can I give nozzle fine mesh and try. Because in my next step glass should move but it doesnt move. And which contact property is good? i have given surface to surface is it ok?

    how to solve this negative eigen value error?

    Hello, When I start next step it stops. normally in next step glass should move in X direction but I dont know it stops may be wrong interaction property. here is attached file. you can check. https://files.engineering.com/getfile.aspx?folder=7061d42c-bfd4-4a16-80c2-f3c436d2dd7e&file=Copy_Copy.inp

    How cn I do Natural Convection?

    Its not possible to put Filament inside because I need conduction between Filament and nozzle. I have tried with small distance between nozzle and Glass but when step-2 starts it stops automatically. https://res.cloudinary.com/engineering-com/raw/upload/v1567408889/tips/All_Together_x8udot.dat

    How cn I do Natural Convection?

    Is it possible with fine mesh to get result in standard(coupled-temperature-displacement)?https://files.engineering.com/getfile.aspx?folder=e6e4de5c-14b4-45b1-9987-b07d62e80664&file=Explicit_All_Part.msg

    https://res.cloudinary.com/engineering-com/raw/upload/v1566900510/tips/Explicit_All_Part_bqh0g7.dat In explicit is it possible to do simulation with big total time in step? like in one step 15 second?

    How cn I do Natural Convection?

    In explicit I have problem with time. I gave total time 15 sec with 0.002 m/s velocity but its stops with the error that it needs more increment.

    How cn I do Natural Convection?

    Hello Sir I got your point. but I have one more problem that after completion of my first step(Material comes down until glass) simulation stops. just start step 2 but it stops in 1 increment only can you just tell me how can I solve this error?

    How cn I do Natural Convection?

    still for convection I'm confused that how to used. Cause the part coming is normally at room temperature and inside nozzle its conduction and the I want to give that extruded material a convection. so can I cut my part with datum plane and then choose only that part?
