Compute the deflection of a spoon held fixed at the end and with a force applied at the top in the negative direction. Set up variables and parameters:

Set up the PDE and the geometry:

Compute the deflection of a beam held fixed at the left end and with a pressure applied in the negative axis at the right end:

Set up a geometry and the PDE:

Solve the equation with a pressure load:

Solve the equation with a force load:

Because the surface area that the pressure and force act on is 0.02 and since the force is equal to pressure per area , the displacements are the same:

Apply a pressure normal to the inside of a pipe. The model domain is a quarter–cross section through a pipe, with matching units of an inner radius , an outer radius and a thickness . At the left boundary, a symmetry constraint is added such that the pipe can move up and down, and at the right bottom, a second symmetry constraint is added such that the pipe can move left and right. A pressure of is acting within the pipe in an outward direction. The remaining boundaries are free to move. Young's modulus is given as and Poisson's ratio is .

In the case where boundary load values have predicates that do not overlap with the region boundary, results may be inaccurate. Set up a PDE:

Set up a boundary load with a discontinuity at and at :

If the geometry does not reflect the discontinuity in the boundary condition, the result will be less accurate. The solution will be more accurate if the region reflects the discontinuities at and at . Set up two meshes:

Solve the equation with two different geometries:

Compare the direction displacement along and :
