Monticelli wrote a helpful summary of the topic in 2016 (The Membrane Bending Modulus in Experiments and Simulations: A Puzzling Picture). Orientation analysis is one of the better techniques as far as time/size requirements.
If you tell me how you want to calculate it, maybe I can help you prepare a script to do it.

The classic way to do that is to extract the power spectrum of thermal undulations in equilibrium for a tensionless membrane patch and compare it to the 1/q^4 law predicted by the Helfrich functional. See for example:

Also, if you have access to lateral pressure distribution across the z direction, you can use that to calculate elastic properties. See here:

Thanks. I will try the Membrane Buckling method to do this.

The paper below might be helpful. It describes a way you can calculate the bending modulus and they make use of an open source software (https://openstructure.org/ )
