(OP)
How to model pad footing or combined footing with strand 7 software? I have tried the plate and brick elements, could not get a good result. With brick elements, how to get soil bearing, shear and moment at certain cross section? Other software like SAFE (FEA software for slab and footing) is very convenient. But i have to use Strand 7 to model. Please help me for this. Thank you!

What you do depends on how much detail you want to go into and the size and shape of the footings. If you are looking at structural design of a straightforward footing it should be adequate to model the footing with beam elements along the footing mid-depth, with offset elements to the base, and model the soil with 8 noded plane strain plate elements, extending far enough so that boundary effects are not significant. Restrain the plates in the X and Y direction at the bottom of the mesh, and X only at the edges.
You will then get the bending and shear in the footing and the soil stresses directly.
Don't expect the results to agree with a traditional simple analysis with a trapezoidal soil pressure distribution, which is really a fiction used for simplifying design.

Do you mean the solver stops with an error, or what?
