Hi ViV,

Could you please let me know the velocity range and which version are you using ?

ViV

Hi Sourav,

I run the simulations with version 2019.4.

The velocity profile can be seen in the picture.

Hi ViV,

I would suggest if you could reduce the element size and try, I hope velocity will not be a problem. ( try reducing the element size, check and let me know if you still get a strange wave).

Hi Sourav,

the waves are no longer so strange, but the element size is not acceptable for a Raw part (!).

Hi ViV,

Oh! that's great, Can you tell me little details about the part, I can get back to you with the correct element size for the part, might be little helpful.

Hi Sourav,

Look at the pictures.

Hi ViV,

For meshing shot sleeve, element size will be in some ratio with cast part elements. See it is defined 3mm element size in run dialog, then internally it calculate the element size for shot sleeve, it wont mesh with 3mm for shot sleeve.

ViV,

One more thing ,As per implementation, we can define element size for cast part, for other parts, it calculate element size automatically or with ratio that is defined in mesh component matter since here we do auto meshing.

Hi Sourav,

Thank you for the explanation.

When will be available ver. 2020.X?

Best regards.
