Gravity in forming simulation

Use Tools Pull down menu: BC manager. See attached screenshot.

Thanks. I am going to try this.

In the Curve ID, what do I have to put if I want the gravity to be during all the simulation? in the values of X the time peiod and in the values of Y, 1 or 9810 ? I mean, I don't know if the function already takes ino account the gravity value or I have to re-write it.

in the screenshot below, I wrote in the curve in the values of Y -9810, and int he X and Y scale factors also, but I get the rows in the positive direcion of Z and I want then in he negative direction. What am I doing bad?

We have one small bug in HyperMesh with respect of this –Ve direction visualization. Check rad file in text pad it would be -9810

SO I have to re-write the value of the gravity (9810) in the curve function and also in the scale x and y ? it w'ont be a double graviy effect?

Hi Aurea,

Create a curve in XY Plots>>Curve Editor for gravity load and recall that curve in Curve ID for creating a gravity load. Maintain Scale X and Scale Y values as 1 itself.

For creating the gravity in negative Z direction (as in your model) , either you can provide -9810 value in the function you are defining or you can input Scale Y value as -1.

I have a curve like that already defined.

but my gavity is in axe Z. do i have to still put -1 in the Y scale? and in the x scale I leave the value of 1, isn't it?

Thank you very much for the help

Aurea,

If the values in the curve are -9810 then let the Scale X and Y values be 1 itself. Then the load will act in negative Z direction.

i am trying as you told me but now the plis move in the Y direction.

it is not a problem that when I define the courbe I give values to X and Y and then I say the gravity mouvement is in Z?

Direction of translation will be the direction you specify.  X and Y are meant for scaling only.

If problem still persist, please share your model 

thank you.

it would be easier but it is a confidential simulation that I am not allowed to share.

you helped me a lot.
