reactor identifies problems before you try to preview or compute the simulation. These problems are displayed in an error window. The following are some common errors that you can avoid. Use the Analyze World button to look for warnings.

• Don't use the default Plane primitive: reactor complains if the plane object is co-planar. The problem is that without any depth, reactor can't accurately compute collisions. Instead, use a Box primitive or use reactor's Plane Primitive object (found in its toolbar).

• Watch for low Mass values: reactor complains if the Mass value for any objects is too low. To fix this problem, increase the Mass value for the identified object.

• Don't have interpenetrating objects: Objects that intersect cause an error in reactor. Make sure that none of the objects intersect with each other.
