triangleAreaConstraint
Adds a triangle area constraint to the body, ensuring that the areas of triangles in the body remain consistent with their initial (rest) areas during simulation.
The constraint is applied by creating an instance of TriangleAreaConstraint, which adjusts the positions of the nodes in the body to maintain the specified area properties. This function allows for optional configuration of the constraint's parameters (such as compliance and iterations) through the provided lambda.
Parameters
configure
a lambda function to configure the properties of the TriangleAreaConstraint being added. Defaults to an empty lambda if no configuration is required.
