Hello,

I am trying to model a moving heat source problem using ANSYS. The problem I have is in determining the velocity of the heat source form the given conditions. Let's say I have:

Normal
0

false
false
false

MicrosoftInternetExplorer4

/* Style Definitions */
table.MsoNormalTable
{mso-style-name:"Table Normal";
mso-tstyle-rowband-size:0;
mso-tstyle-colband-size:0;
mso-style-noshow:yes;
mso-style-parent:"";
mso-padding-alt:0in 5.4pt 0in 5.4pt;
mso-para-margin:0in;
mso-para-margin-bottom:.0001pt;
mso-pagination:widow-orphan;
font-size:10.0pt;
font-family:"Times New Roman";
mso-ansi-language:#0400;
mso-fareast-language:#0400;
mso-bidi-language:#0400;}

TIME,1 

DELTIM,
1, 1, 1,ON

what will be the velocity? If I change Time,1 to time 20, the rest being the sam, I get the following error message:"present time 1 is less than or equal to the previous tine in a transient analysis". 

 Can anyone help with this, pls?

Thanks.
