I need help !!! I am combining and nothing.

I have four wall:

wall-1

wall-4 If it's possible to moving wall-4 (direction to wall-1) without uses UDF file. Which walls is stationary and moving. And which parameters in "Dynamic Mesh" I must determine???.

Regards

Sorry, but my schematic is not clear. This is square which consist od four walls (top - wall1, bottom -wall4, left -wall2, right-wall3).

Regards

only wall-4 you don't need use stationary set layering

you can use in-cilinder for tests or try this udf

#include "udf.h"

static double linear;

DEFINE_CG_MOTION(linear, dt, vel, omega, time, dtime) { real w = 300,a=0.1;

NV_S (omega,=, 0.0);

linear = w*sin(w*CURRENT_TIME); vel[0] = linear; }

0 is the direction of moving

0 is x 1 is y 2 is z

Hi

But I cannot compiled:

..\..\src\pist.c(8) : error C2373: 'linear' : redefinition; different type modifiers

..\..\src\pist.c(4) : see declaration of 'linear'
