why does my simulation slow down after a while ?

im using simmechanics to model a robot , the simulation slows down after about 70 seconds, i'm visualizing the model, i think its cumulative data, probably the visual simulation is the problem , any idea how to clear unwanted variables while simulating the model ? and thank you

How are you preforming the visualization? If you keep adding new images to an axes, without calling cla in between, then it will slow down because all those images get stored in the axes. Subsequent images do not replace the image in there.

visualization is done using simmechanics visualization feature, i don't add images, i only provide .stl files or it uses default ellipsoids, if i don't use the visualization feature the simulation is very fast.
