Ventsim™ 4.1 is the latest version of the best-selling Ventsim™ mine ventilation simulation software and includes many new features and improvements to help users build better models, create more accurate simulations and save time and money.

New features of Ventsim™ 4.1 include, what developer Chasm Consulting says is 300% faster simulation for VentFIRE and Dynamic Simulation. This includes a revised optional ‘Quick’ method and ‘Quick’ preset settings for VentFIRE.

Open Deswik.CAD Ventsim Export files is another new feature. The latest version of Deswik.CAD can now export a fully scheduled mine plan into a Ventsim file, complete with Ventsim airways with the correct size and shape. Addition wireframe graphics such as stope or orebody can be included as references. Deswik.CAD automatically assigns layers and different stages to show mine development over time. This is a real time saver for Deswik/Ventsim users!

Reference object graphics can now be assigned to Ventsim Primary and Secondary layers, and stages. Use the SELECT > REFERENCE button to fence or click reference graphics, then press the EDIT button.

There are also improvements to the airflow simulation algorithm for difficult-to-balance models.

Ventsim 4.1 is available now and there is a free upgrade for current maintenance holders.

Chasm Consulting will be attending the SME Annual Conference in Phoenix, USA next week. Chasm will be providing information on all of its software products, as well as conducting demonstrations of Ventsim 4.1 and Pumpsim™ software.

Pumpsim, has now been released as version 2, incorporating a brand new high speed solving engine together with additional features for modelling tank flow, valves and demand devices such as machines and sprays.

Using the familiar interface of Ventsim, Pumpsim is built to help design, model and plan water and pumping networks.

Chasm Consulting says: “Few mines we see have good plans for their water reticulation, and often suffer delays and downtime from insufficient or inconsistent water supply and pressure. Or worse, suffer from flooding or excess water due to inadequate pumps or pipe sizes.”
