Hello all,

I'm simulating LDED in Flow3D. There are 'Contact Angle' and 'Contact Angle to Solid Phase' under Material>Surface Tension in Flow3D Weld. What's the difference between these two?

I tested different 'Contact Angle' (0-120 degrees) but didn't see a big difference in bead shape. After I put some numbers in 'Contact Angle to Solid Phase', the bead shape changed significantly but the liquid didn't wet the substrate. So I'm wondering how these two options affect the bead shape.

Could anyone give me some guidance? Thank you in advance!
