buildDampingMatrix not implemented:

[BIN868]

When I run the simulation, the following warning appears“ buildDampingMatrix not implemented: for compatibility reason, the deprecated API (addBToMatrix) will be used. This compatibility will disapear in the future, and will cause issues in simulations. Please update the code of AdaptiveBeamForceFieldAndMass to ensure right behavior: the function addBToMatrix has been replaced by buildDampingMatrix”
The following is the XMl file.
