Problem

What does the warning in dynpac module refer as negative load in certain joints from space load distribution?

Solution

This is happening because you have applied the space load in an eccentric location with respect to the distributed joints.

So, due to this eccentricity, a push pull scenario is developing and when SACS internally distributes the load, a set of up down force is generated.

This set of force when converted into mass, the negative value of mass (a scaler quantity) is created within the dynpac module. Hence, such warning is provided.

To avoid this, you need to ensure that the distribution joints are selected in such a way that the load eccentricity does not develop.
