Hey all,<\/p>\n

Today I feel a bit sad since my simulation is not outputting the expected results. But I am not worried since someone might be able to help me on this forum :). I have been browsing the internet to find an answer but did not succeed. I think i am not noticing a subtle problem\/small error.<\/p>\n

I am trying to simulate a steel ball drop on a plate, I did this with explicit dynamics but actually want to do it with a transient structural analysis now. To start off small i just want to simulate the ball hitting the plate when it is fixed on all the edges <\/p>\n

For the composite plate, i use an isotropic linear elastic model. The problem is that the ball just passes through the plate and no contact is detected. The contact is defined at the ball’s surface and the surface of the plate where the plate is the target but i have changed this up to check it. Two errors occur: The first one is this one where the ball travels in the other direction when it start off contacted to the plate:<\/p>\n

\"\"<\/a><\/p>\n

Another thing that happens is that the ball passes trough the plate and no contact is detected.<\/p>\n

Is it possible to fix this?<\/p>\n
