## Contact-mode interfaces in Simcenter STAR-CCM+

In CFD simulations involving several parts, such as conjugate heat transfer (CHT) or Fluid-Structure Interaction (FSI), you need to establish a connection between the different parts to enable exchange of data. This connection is typically handled through an interface. In Simcenter STAR-CCM+ interfaces can be of either boundary-mode or contact-mode type. In this week’s blog […]

## Reduced Order Modeling for 2D Static Fields

In this blog article we explore the capabilities of image-based Reduced Order Models, or 2D Static Field models as they are known, inside Simcenter Reduced Order Modeling (ROM), and go through the necessary steps to export 2D field data from Design Manager.     Simcenter Reduced Order Modeling is a software tool which creates mathematical

## Pressure outlet options in Simcenter STAR-CCM+

A common recommendation when running CFD simulations is to position your boundary conditions far from your area of interest, to not influence the results through stiff numerics. But sometimes this can be difficult (or computationally expensive) to achieve. A common challenge is the pressure outlet, which typically acts as the environmental or far field pressure

## Introducing Volupe’s Nusselt number calculator

Estimating convective heat transfer coefficients is a commonly recurring task when running thermal analyses. For many applications, standardized empirical correlations can be used to obtain estimates of these coefficients based on the Nusselt number, but crunching the numbers can sometimes be a tedious task. Hence, as part of our continuous stride to simplify the everyday

## Initializing with existing solutions in Simcenter STAR-CCM+

Sometimes you have simulation results that would be helpful to use as a starting point for another simulation. Perhaps you want to fine tune a boundary condition but save time by using a better starting guess, or maybe you want to run a single phase simulation and use the solution to initialize a multiphase case?

## Simcenter STAR-CCM+ 2310 multiphase news

Once again, in proximity to the release of the new Simcenter STAR-CCM+ version, we will venture into the news relating to multiphase simulations. Simcenter STAR-CCM+ 2310 was released this Wednesday and contains several exciting news in the multiphase department. Let’s jump right into it. We will start with Eulerian type model news and then move

## Faster VOF simulations by avoiding time-consuming start-up effects

Running VOF simulations typically requires a transient approach, but sometimes you are not necessarily interested in analyzing the start-up effects of a free-surface flow, but rather just the long-term characteristics when the flow pattern has reached a quasi steady-state. Reaching this quasi steady-state can be computationally expensive and time-consuming, sometimes to the point of infeasibility.
