## Simplification algebraically siderules...

Hi all,

In short, I want to use

'ss' expression(1)

to simplify

'kappa' expression (2).

At the moment, I can only archieve it through solving for each variable and get to expression (5).

simplify using siderules failes in this case. Is there another way to do it?

Thanks,

Casper

## How to plot the energy of an ion as a function of ...

Hi,

Struggling to get my head round how to plot the results of the follwoing, as it seems I have 4 variables...

I have a data file containing the results of the following problem:

1) Consider a cube. Each side (a,b,c) has a length of 1 unit.

2) Place an ion (0,0,0) where [a,b and c intersect] and find the associated energy at that point.

3) Move the ion to a point 0.05 units along side a to (0.05,0,0) and re-find the associated energy.

Hi,

I need to model the MapleSim ground as a hard ground. For example when the robot swing leg hits the ground, it should not have negative vertical position. Basically, the robot will move on a surface.

Thanks...
