I am trying to apply a force in the axial direction so as to see the top body slide over the bottom one and tip down as it crosses the bottom body. But My top body seems to be dragged upwards in spite of applying axial Load. I tried restricting displacement in other directions. This worked but then the tipping of the top body cannot be observed then. Can you suggest me what could be the problem? Its the same problem I am encountering in LS-DYNA as well.

I will try to attach sufficient screenshots

In ANSYS with force load being applied, it generates no result

It would help if you put labels on the image to show the support faces, the faces with force load and what you mean by the axial direction. Is that Y axis?

The red body is given a fixed support and in y direction a load is applied on the face of blue body as marked in the figure. simple comparison is to that of a block sliding over a table.

The picture previously attached was how it deflects on such a load being applied.

Also the friction provided at the contact seems to produce no difference. with 0 coefficient of friction or 0.2 coefficient of friction, the results produced are same

[peteroznewman]

Do you have gravity turned on to provide the normal force to generate a frictional force?

Thanks a lot. I haven't thought of this. I will try this and see
