library for simple systems

hiii i am new to this field and am doing a small project involving moving boundaries. now basically i intended to simulate everything in matlab, but matlab can handle pdes only upto order 2. can you suggest where i can find if possible free libraries of pde solving codes in 3d unsteady states. the method of solution is not very important here but the formulation shouldnt be so general that i spend most of the time just simulating the flow. if you have such a code, could you please send it to me at dibyadeep@gmail.com. if possible the code should be in .m format. and if the code is not in .m format is it possible to transfer the information generated into matlab format for visualisation purposes. how do you do that.

thanking you
