One missing feature of num3sis was the ability to record video of the simulations. With the new dtkVideo layer and new Actor Nodes in the composer (see previous post), we have now several ways to achieve this. The first possibility … Continued
One new feature recently added in num3sis is the ability to configure the actors directly in the composition space. Currently, only field actors are configurable. Mesh and volumes should be soon available. 5 nodes are available, for scalar and vector … Continued
Num3sis framework provides a large amount of tools devoted to numerical simulation. It is dedicated to end users such as researchers or engineers but its modular design enables more advanced people to develop more quickly their own functionalities.
In some circumstances, e.g. a distributed computation, it may be useful to monitor what happens on distant nodes of a cluster. To do that, one need to instantiate as many views as working slaves.
The composer is the masterpiece of num3sis platform, since it allows to define the computational scenario by connecting nodes and corresponding implementations in plugins. In the numerical experiments carried out so far, some limitations have been encountered, which have motivated … Continued
The accuracy of a solution depends strongly on the mesh used for the resolution of the state equations. Since the computations based on a uniformly refined mesh are highly expensive, local refinement strategies based on error estimation are more and … Continued
Simulate pedestrian traffic enables scientists to predict the behavior of pedestrians to reach the exit in an emergency situation. We use a macroscopic model considering the density of pedestrians that obey a conservation law. A first simulation have been … Continued
The Eikonal equation is a non-linear partial differential equation, which is a special case of the Hamilton-Jacobi equation and can be written in its simple form: |Grad(Phi(x))|=1, x in R^n The solution Phi can be viewed as the travel time … Continued
dtk updated its composition loading mechanism: see dtk’s blog. This development was a preliminary step towards the numStore.
The first event around num3sis was organized during the first week of October. As num3sis is meant to be a multi-domain platform, this event gathered people from various horizons. This coding sprint mainly aimed at shared experiences in software engineering, … Continued
