Using Finite Element Method (FEM) techniques in architectural projects can be tough for students. Let's break down some of the challenges they face:

1. Learning Complex Software: Students often find FEM software complicated. Figuring out how to use these tools takes a lot of time and energy, which can distract them from being creative in their designs.

2. Grasping the Theory: It's really important to understand the math behind FEM. Many students struggle to see how theories, like stress and strain, relate to real-life situations. For example, the formula for stress is $\sigma = \frac{F}{A}$. But when dealing with 3D structures, it gets even trickier, which can cause confusion.

3. Modeling Accurately: Making precise models of shapes and conditions is key. However, students often don't get this right. Mistakes in modeling can lead to bad results, which might make the structure weak or unsafe.

4. Understanding the Results: Even when simulations are done right, figuring out the results requires careful thinking and experience. If students don’t interpret them correctly, they might make poor design choices.

To deal with these problems, students can:

• Join workshops that focus on learning the software.
• Work together with classmates to better understand the theories.
• Ask teachers for help to improve modeling skills.
• Practice looking at and discussing results carefully to get better.

In the end, being persistent and ready to learn from mistakes can lead to successfully using FEM in architectural projects.
