 ===== Node properties =====
 Node properties are defined by a structure array to assign properties to nodes, such as boundary conditions, applied loads, and inertia. The usage is ''nprops(i).field = value;'' to assign property ''field'' with value ''value'' to node ''i''. For a full syntax list with all possible inputs, see [[full_syntax#3. Node properties|SPACAR Light syntax]].

 Furthermore, we would like for the parallel flexure guide to start 10mm deflected to the left and let it move 20mm to the right. For this purpose, we pre-describe the position of node 2 in x-direction:
 <code matlab>
-nprops(2).displ_initial_x =-0.01; %start with node 2 displaced 10mm to the left
+nprops(2).displ_initial_x =-0.01; %start with node 2 displaced 10 mm to the left
-nprops(2).displ_x =         0.02; %displace node 2 20mm to the right
+nprops(2).displ_x =         0.02; %displace node 2 20 mm to the right
 </code>
 At last we apply a load of 5N in Z-direction on node 2 and 3
 <code matlab>
-nprops(2).force_initial = [0 0 5]; %initial load of 5N i z-direction
+nprops(2).force_initial = [0 0 5]; %initial load of 5N in z-direction on node 2
-nprops(3).force_initial = [0 0 5]; %initial load of 5N i z-direction
+nprops(3).force_initial = [0 0 5]; %initial load of 5N in z-direction on node 3
