Abstract: To determine a corrected flow rate value of a mobile phase flowing in a liquid chromatography (LC) system, a flow rate of the mobile phase at a selected reference position in the LC system is measured to produce one or more flow rate values. A model of the LC system is applied to the flow rate value(s) to determine the corrected flow rate value(s). The model includes a distribution of capacitive elements and resistive elements arranged according to a topology of the LC system. The capacitive and resistive elements are representative of system and solvent properties affecting flow rate while operating the LC system. The system and solvent properties may be properties affecting the flow rate while operating the LC system under dynamic conditions.

Abstract: Unlike existing methods that rely on manual procedures for repairing finite element meshes in computer-based simulations, embodiments automatically repair finite element meshes for use in simulations of real-world objects. One such embodiment begins by identifying a non-compliant mesh element in a finite element mesh and extracting a mesh patch from the finite element mesh that includes the identified non-compliant mesh element. To continue, an invariant patch description for the extracted mesh patch is generated and a repair solution corresponding to the generated invariant patch description is obtained from a database storing pre-determined repair solutions. In turn, the mesh patch in the finite element mesh is repaired using the obtained repair solution.

Abstract: A design application interacts with an end-user to generate design problem geometry that reflects a design problem to be solved. Various design objectives, design constraints, boundary conditions, and other design criteria may be associated with the design problem geometry via the design application. When the design problem is sufficiently well defined, a client-side solver generates a solution approximation using a coarse multi-objective solver. The client-side solver favors speed over accuracy, and so the solution approximation provides only a rough representation of various attributes of potentially feasible design solutions. Based on the solution approximation, the end-user may correct any omissions, mistakes, and so forth, before executing pay-per-service cloud-based parallel solver.
