			<h2>Description</h2>
			<p>The <em>smd/tri_surface</em> style calculates contact forces between SPH particles and a rigid wall boundary defined via the
			<a class="reference internal" href="fix_smd_wall_surface.html"><span class="doc">smd/wall_surface</span></a> fix.</p>
			<p>The contact forces are calculated using a Hertz potential, which evaluates the overlap between a particle
			(whose spatial extents are defined via its contact radius) and the triangle.
			The effect is that a particle cannot penetrate into the triangular surface.
			The parameter <contact_stiffness> has units of pressure and should equal roughly one half
			of the Young’s modulus (or bulk modulus in the case of fluids) of the material model associated with the SPH particle</p>
			<p>The parameter <em>scale_factor</em> can be used to scale the particles’ contact radii. This can be useful to control how close
			particles can approach the triangulated surface. Usually, <em>scale_factor</em>=1.0.</p>
			<hr class="docutils" />
			<p><strong>Mixing, shift, table, tail correction, restart, rRESPA info</strong>:</p>
			<p>No mixing is performed automatically.
			Currently, no part of USER-SMD supports restarting nor minimization.
			rRESPA does not apply to this pair style.</p>

			<h2>Restrictions</h2>
			<p>This fix is part of the USER-SMD package. It is only enabled if
			LAMMPS was built with that package. See the <span class="xref std std-ref">Making LAMMPS</span>
