One of the first things I had to learn when working with Google Cloud for my FEniCS simulations was how to properly manage VM instances. Unlike my local machine that’s always on, cloud VMs need to be actively managed to control costs and maintain my work. Here’s what I learned about starting, stopping, and deleting instances.

I’ve been exploring Google Cloud computing for large-scale synthetic data generation, and one of my first challenges was getting FEniCS running on a cloud VM. After some trial and error, I figured out a clean approach using Conda that avoids messing with system-level Python installations. Here’s what I learned along the way.

As I continued exploring Google Cloud for my FEniCS simulations and synthetic data generation, I needed to figure out the best way to connect to my VMs. I discovered there are multiple ways to SSH into a Google Cloud VM, each with its own use case. Here’s what I learned about the two main methods I use.

As I’ve been learning Google Cloud for my FEniCS simulations and synthetic data generation work, I’ve learned some critical lessons about cost management—some of them the hard way. I’ve heard horror stories of researchers accidentally burning through $1000+ before they even realized what happened. Here are the best practices I follow now to avoid costly mistakes.

Reading a research article is an art. Even though we spend quite a good amount of time doing that, but no one really teaches the approach that we should abapt. And the irony is, there are actually some standard and optimal ways of reading a research paper.

In Python, whenever you wish to rotate any plot, you can do that with the help of Rotational Transformation. In Rotational Tranformation, the input coordinate matrix is multiplied with a Transformation (Rotation) matrix.

Being a computataional enigneer, your day will remain incomplete without typing custom codes in code-editor or doing simulations. But, very often, you can fall into the trap of shifting from actual work to random web surfing. The two fold effect of this will be, your time will fly away without any productive outcome and you can still feel like you are doing something.

When analyzing wave propagation inside a periodic structure, one may consider the analysis over a single section or a unit cell instead of the complete domain, by considering the appropriate periodicity at the boundaries. This approach reduces the domain of analysis and simplifies the problem.

Whenever you create content for any website, you wish that your content comes first whenever a user searches for that in a search engine like google.com. To do that, one uses a certain optimization process called Search Engine Optimization (SEO).
