This problem is a Test problem for the new DObject_Floating Text. 2007-Feb-15 Brockman IWP3
Test for the Xacceleration vector zero. If the problem exists, then the xaccel vector jumps at t=0.3.
Very simple test for Euler calculations. It's important to remember that the Initial Displacement and Velocity can be dynamic equations and possibly more complicated than just fixed numbers. This means they would be based on inputs values, which is illustrated here.
Shows the difference between v2 and v3 when self-referencing properties across the x and y paths. Note that this was a quirk in V2 that I had to port over to V3 - after the xpath calc, the disp and velocity are written back into the variable space and made visible to the Y calculator. brockman 2007-Jun-06
TEST for hidden inputs. Make sure that the value of the hidden input is set to the initial value on initial problem load, and not just reset.
Very simple test for Rk2 calculations. It's important to remember that the Initial Displacement and Velocity can be dynamic equations and possibly more complicated than just fixed numbers. This means they would be based on inputs values, which is illustrated here.
Very simple test for Rk4 calculations. It's important to remember that the Initial Displacement and Velocity can be dynamic equations and possibly more complicated than just fixed numbers. This means they would be based on inputs values, which is illustrated here.
