Passage DEM - Discrete Element Method

Technalysis® Engineering and Passage® CFD Software

Since 1985, Technalysis, Inc. has been providing the latest technology and practical solutions to solve the clients' problems, within their schedule and budget. Technalysis specializes solving complex fluid flow and heat transfer problems using computational fluid dynamics (CFD) and other advance CAE solutions.

We have worked with many small and large engineering groups. These include automotive, electrical, appliance, equipment, food, chemicals, and pharmaceutical companies. Our consulting group utilizes in-house developed, engineering design CFD software called Passage; also licensed as consumer software products. For a brief list of companies that we have provided consulting and software solutions,  please refer to our list of clients. 

Technalysis® Advantage

By combining consulting and software under one roof, Technalysis offers a technology path from problem solving, to software delivery and the training of a client to solve similar problems.

Advantages of Passage DEM+FLOW

By coupling PASSAGE: Discrete Element Modeling (DEM) and 3D FLOW software a variety of problems can be solved which can not be treated by using either one model individually. This capability allows modeling of liquids, gases, solid particles and their mixtures for many industrial problems in both micro and macro scales. It can be applied to process modeling of mixing, wetting, coating, filtration, fermentation and filling operations for applications in food, pharmaceutical, chemical, metals, plastics, glass, ceramics, powders processing and emission control. 

DEM and FLOW modules can be coupled in a variety of ways depending on the application.

Advantages of using Passage 3D FLOW with 1D SYSFLOW

Simultaneous use of PASSAGE: 3D FLOW and 1D SYSFLOW software provides a practical tool for solving complex flow and heat transfer problems. This capability allows modeling of complex systems followed by detailed analysis of sub-systems and components. Design process start with developing the overall concept, detailing its components and ensuring that the overall performance and efficiency targets are met. Using PASSAGE: SYSFLOW one can develop an initial concept, perform sensitivity analysis to determine its critical components and set directions and further development. One can then proceed with detailed design using PASSAGE: FLOW at the same time refining SYSFLOW models and testing prototypes.
