WebDescription. CVPack is a Python package that provides pre-defined collective variables (CVs) for the powerful molecular dynamics engine OpenMM. All these CVs are subclasses of OpenMM's Force class and, as such, can be directly added to a CustomCVForce or used to define a BiasVariable for Metadynamics, for instance.

WebOpenMM uses the following units everywhere. These units have the important feature that they form an internally consistent set. For example, a force always has the same units (kJ/mol/nm) whether it is calculated as the gradient of an energy or as the product of a mass and an acceleration. WebbiasWidth (float or unit.Quantity) – the width (standard deviation) of the Gaussians added to the bias during metadynamics. periodic (bool (optional)) – whether this is a periodic variable, such that minValue and maxValue are physical equivalent. gridWidth (int (optional)) – the number of grid points to use when tabulating the bias function.
