Thanks for the answer. I guess I missed the cross button ! <div>(The whole point was that I didn't want to write out the cross product anymore !! :) <br><br><div class="gmail_quote">2009/3/4 Scott, W Alan <span dir="ltr"><<a href="mailto:wascott@sandia.gov">wascott@sandia.gov</a>></span><br>

Hello<br>
<br>
The + sighs between cross terms should be replaced by - signs as follows:<br>
i ( a_2b_3 - a_3b_2 )<br>
+ j ( a_3b_1 - a_1b_3 )<br>
+ k (a_1b_2 - a_2b_1 )<br>

I don't know if this is correct, but I took a quick attempt at making a cross product. I am using the dataset can.exo. In the calculator, I am trying to create the cross of the DISP and ACCL vectors. Here is the formula:<br>
<br>
iHat*(DISPL_Y*VEL_Z+DISPL_Z*VEL_Y)+jHat*(DISPL_X*VEL_Z+DISPL_Z*VEL_X)+kHat*(DISPL_X*VEL_Y+DISPL_Y*VEL_X)<br>

I am trying to do a vector product with the Calculator, but this seems to fail "Error deciding between ambiguous operators".<br>
Is there a way to do vector products ? Or is this something that needs to be implemented ?<br>
