The Advanced distribution settings option can be activated for the load transfer surfaces with the "Stripe" load transfer direction. Thus, the following text boxes become accessible in the "Parameters" section:
- Stripe width
- Smoothing factor
- Minimum number of stripes on surface
The meaning of these parameters will be explained using a simple example.
What are stripes?
Stripes are used to divide the load transfer surface into surface strips along its x-axis, y-axis, or both axes. The load transfer to underlying objects is then calculated individually for each stripe.
Compared to the "Isotropic | FEM" method, this method has the advantage that the distribution loads can be calculated in a very short time. However, this is a simplified method, as the member or line loads always have a constant distribution within a stripe.
Stripe Width
You can use the "stripe width" parameter to control the width of a stripe. In the following image, different values for the stripe width were applied, which illustrate the influence.
What is a smoothing factor?
The smoothing factor controls how much the distribution loads should be smoothed across the surface strips. A low value means little to no smoothing. The distribution loads are then available, as they were calculated using the stripe method. On the other hand, a high value means that the distribution loads are strongly smoothed.
The following image shows the load distribution for very small and very large smoothing factors.
Minimum Number of Stripes on Surface
This parameter allows you to increase the number of area strips to a minimum value per surface, independently of the defined surface strip width. By default, the minimum number is 20. However, you can also reduce this value, if necessary.
