Hi everyone,

I want to simulate a moving load on a surface. 
The diemensions of the surface are given below.

I want to apply pressure load along the Y-coordinates. For this purpose i am using the following script.

total_time = 10
time_step = 10
time_inc = 1
V_p = 2 
Radius = 2
PV = 100

/PREP7

et,100,154
cmsel,s,surface1
type,100
esurf
allsel,all                              

/solu   

*Do,I,1,total_time,1

Y_Local = V_p*TIME

wpcs,-1,0
wpof,,Y_Local 
esel,s,ename,,154
sfed,all,,pres
nsle
nsel,r,loc,X,-10,10
nsel,r,loc,Y,0,2
esln,r
sfe,all,,pres,,PV
allsel,all
outres,all,all

TIME,I
SOLVE

*enddo

In the first step everything is good but the load is not moving.

Here is the result.

I am using ANSYS WORKBENCH 2023 R1.

If there is any other alternative, Please recoomend me. 

Any kind of help will be highly regards.
I thank you all

Hi

The below is one way of doing this (you would need to split the face into many faces say 10).

/forum/forums/topic/moving-load-geometry-for-each-step-of-a-steel-staircase/

Also search the Ansys forum and the internet for moving load

All the best

Hi Erik,
Thank you for your response.

This is just a simple geometry and i know it is easy to split the surface into different sections, But my simulation is a bit complicated. I am able to run the pressure load in the form of a cirlce. But in real problem, i should apply the pressure on a selected square area.
