Keynote Video: Moving Beyond Simulation for Biopharma Applications

Brianne Costa March 21, 2018

Pablo Rolandi from Amgen delivered a keynote presentation at the COMSOL Conference 2017 Boston. The topic? How Amgen is moving beyond modeling and simulation for biopharma development. Rolandi shared five examples that illustrate this idea across both biologic and synthetic medicine applications. If you missed his presentation, you can watch a recording of the video and read the highlights of what he discussed here.

We have already discussed different ways to create geometry objects of irregular shapes on the blog. In this blog post, we will demonstrate an incredibly powerful alternative approach by using interpolation functions. Instead of creating geometry objects, we will indirectly define the irregular shape by taking advantage of the spatial variation of a material property in the object we want to study.

The boundary element method (BEM) is included in the Acoustics Module as a physics interface. This interface, available as of version 5.3a of the COMSOL Multiphysics® software, can be seamlessly combined with interfaces based on the finite element method (FEM) to model, for example, acoustic-structure interaction problems. This functionality expands the range of problems that can be solved with the Acoustics Module. Here, we look into the BEM functionality, examples, and BEM-specific postprocessing.

Nonisothermal flow combines CFD and heat transfer analysis. In cases where the temperature of the fluid at an inlet is a known quantity, a Temperature boundary condition can be used. However, there are some important situations where this is not the case, and an Inflow boundary condition can improve the model accuracy and reduce the computational cost of the simulation. Here, we review how this more sophisticated thermal boundary condition can be set at a flow inlet.

“The important thing is to not stop questioning. Curiosity has its own reason for existing.” –Albert Einstein A passionate and curious intellectual, Albert Einstein is considered one of the most influential physicists of the 20th century. The German-born mathematician and physicist made numerous discoveries throughout his lifetime. Most notably, he developed the special and general theories of relativity. For discovering the law of the photoelectric effect, he earned a Nobel Prize in Physics in 1921.

Guest blogger Mandar Gadgil of Noumenon Multiphysics discusses modeling phase change in a thermosiphon. Thermosiphons have been used for keeping houses warm since the 1800s. These devices use central heaters and pipe networks that carry water and steam to different rooms. The cool part (figuratively) is that no pump is needed for fluid transport — convective currents induced by the heater located at the bottom of an installation are enough. Let’s discuss modeling thermosiphons using a “pseudofluid” with temperature-dependent properties.

Many types of analyses benefit from running the COMSOL Multiphysics® software on high-performance computing (HPC) hardware. This is one of the main reasons behind the Cluster Computing node, which helps seamlessly integrate the COMSOL® software with any kind of HPC infrastructure, while maintaining the convenience of a graphical user interface. In this blog post, learn how to run large simulations remotely on HPC hardware directly from the COMSOL Desktop® graphical environment.

Additive manufacturing has a wide array of applications, such as creating custom medical devices, aerospace components, and artwork. With the list of potential uses continuing to grow, it’s important that this type of manufacturing can keep up with the demand. However, analyzing and optimizing this complex process can be difficult. What can engineers do to overcome this challenge?

In 1801, the building around a glassmaker apprentice named Joseph von Fraunhofer collapsed, trapping him in rubble. While he didn’t know it at the time, this dramatic event (and resulting encounter with a prince-elector and politician) set him on the path toward improving the field of optics…

The foundation of a tunnel, dam, building, or other structure can be analyzed with a method called triaxial testing. Performing triaxial tests before, during, and after construction helps to ensure that structures are safe and reliable. To better understand the mechanics of soil and improve a structure’s stability, you can model the loading and unloading curves for a triaxial testing apparatus and test the soil’s model parameters in the COMSOL Multiphysics® software.
