Abnormal behavior when using different denseMode

[ChloeZPan]

When I use DHSPH and set denseMode to 2 (dense sampling), the fluid will act incorrectly. The particles seem to have an outward force. I am wondering why this will happen. Thank you!

I encountered the same issue. Have you resolved it now?

Probably due to the dense sampling, the density for some particles is already higher than the rest density at the beginning of the simulation.
