Zero tension iteration options
If a mat is flexible or there are large overturning loads then the springs may initially be resisting tension. You can reduce this tension by iteration.
Zero tension iterations use an "accelerator" factor to make convergence faster. An accelerator value of 1 results in no acceleration, while a value that is too large may result in wild oscillations instead of convergence. RAM Concept calculates the accelerator value as follows:
accelerator = (T j / T i )power ≤ maxAccelerator

Iterations to use The number of iterations used in calculations. The higher the number of iterations, the closer the tension is to zero.
Accelerator Power The power in the above formula; typically this is 1.
Max. Acceleration The maximum allowed acceleration.
