% This is a parameter sweep study of the effect of the number of elements
|
|||
% and element cross sectional area on the displacement at the tip of a
|
|||
% cantilevered truss.
|
|||
%
|
|||
% Inputs:
|
|||
%
|
|||
% nNum: Number of nodes to try along bottom cord (scalar)
|
|||
%
|
|||
% aNum: Number of cross sectional areas to try (scalar)
|
|||
%
|
|||
% Outputs:
|
|||
%
|
|||
% nVals: vector with the number of nodes tested
|
|||
%
|
|||
% aVals: vector of cross sectional areas tested
|
|||
%
|
|||
% peakVals: maximum deflection at the truss tip for each combination of
|
|||
% nVals and aVals
|
|||
%
|
|||
% computeTime: parfor-loop computation time
